Tag Archives: 10mm

The 10mm Automatic cartridge, once a niche caliber on the verge of commercial obsolescence, is undergoing a significant renaissance in the United States firearms market. This report provides a comprehensive analysis of this resurgence, identifying the top 20 most popular firearms chambered for the cartridge and the key market dynamics driving their success. After decades as a cult classic, the 10mm Auto has firmly established itself in several key market segments, transitioning from a failed law enforcement experiment into a premier choice for discerning civilian shooters.

The primary drivers of this market expansion are threefold. First and foremost is the 10mm’s ascendance as the preeminent semi-automatic cartridge for backcountry defense. In regions with large, potentially dangerous predators, consumers are increasingly choosing 10mm handguns over traditional large-caliber revolvers, valuing the significant increase in magazine capacity and the speed of reloading offered by a semi-automatic platform.¹

Second, the cartridge has carved out a substantial and growing niche in handgun hunting, where its combination of high velocity, flat trajectory, and substantial muzzle energy makes it an effective and ethical choice for medium-sized game like deer and wild hogs at appropriate distances.³

Finally, the 10mm possesses a powerful enthusiast and tactical appeal. Its unique history, association with firearms legend Jeff Cooper, and its brief but storied adoption by the FBI have created an enduring mystique. This “enthusiast mindshare” is rooted in its objective performance as one of the most powerful semi-automatic pistol cartridges available, offering magnum-level energy in a modern platform.³

A critical catalyst for this resurgence has been modern firearm engineering. Advancements in polymer frame technology, integrated steel chassis systems, and improved ergonomics have made the potent cartridge’s recoil far more manageable for a broader range of shooters.⁶ This has democratized the 10mm, moving it beyond the realm of “experts only” and into the mainstream. Paradoxically, the market decline of its derivative cartridge, the.40 S&W, has also cleared a path for the 10mm’s success. As the.40 S&W lost favor in law enforcement and became viewed by many enthusiasts as a compromise, the 10mm re-emerged as the authentic, “full-power” parent cartridge, attracting consumers seeking maximum performance.³

Our analysis indicates that the current market is dominated by modern, high-capacity, polymer-framed, striker-fired pistols, with the Glock 20 platform serving as the long-standing benchmark for reliability and market penetration. However, the 1911 platform maintains a powerful hold, particularly within the handgun hunting segment, while pistol-caliber carbines (PCCs) represent the fastest-growing and most dynamic segment, unlocking the cartridge’s full ballistic potential.

Detailed Market Segment Analysis

The 10mm Auto market is not monolithic; it is comprised of several distinct segments, each with its own leading products, consumer profiles, and value propositions. The following analysis examines these segments to provide a granular understanding of the competitive landscape.

The Polymer Vanguard: Modern Striker-Fired Dominance

The rise of the 10mm Auto from niche cartridge to mainstream powerhouse is inextricably linked to the development of modern, high-capacity, polymer-framed pistols. These firearms solved the two primary issues that historically plagued the 10mm: low capacity in 1911-style frames and the punishing recoil that early all-steel designs struggled to mitigate effectively without excessive weight. Today, this segment represents the largest portion of the 10mm market, driven by the demand for reliable, high-capacity sidearms for backcountry defense and tactical applications.

The competitive dynamic within this segment illustrates a maturing market. While Glock established the foundational template of a reliable, high-capacity polymer 10mm, its primary competitors have found success not by cloning this template, but by systematically addressing its perceived weaknesses. This has led to a market where consumers can select a firearm based on nuanced preferences for ergonomics, recoil impulse, or factory-installed features, rather than just basic functionality. Smith & Wesson directly targets Glock’s ergonomics, SIG Sauer competes on recoil mitigation, and both Springfield Armory and FN focus on delivering a more complete, feature-rich package out of the box. This evolution from a utility-driven to a performance-driven market signals the 10mm’s firm establishment in the consumer consciousness.

Glock 20 (Gen4/Gen5)

The Glock 20 is, without exaggeration, the firearm that saved the 10mm Auto from commercial failure. Introduced in 1990, it provided a platform that was both affordable and, most importantly, durable enough to withstand a steady diet of full-power 10mm ammunition—something early 1911s struggled with.⁵ For nearly three decades, it was the default choice for anyone seeking a high-capacity 10mm, establishing itself as the undisputed benchmark for reliability and durability in the category.¹

Its market dominance is driven by this reputation for “plug-and-play” reliability; it is known to function flawlessly with a vast range of ammunition, from lighter range loads to heavy, hard-cast hunting and defensive rounds.¹⁰ This proven performance has made it the go-to choice for backcountry defense, famously being adopted by Denmark’s elite Slaedepatruljen Sirius (Sirius Sled Patrol) for defense against polar bears.² Furthermore, the Glock 20 benefits from the most extensive aftermarket in the industry, allowing for limitless customization.

Common criticisms center on its ergonomics, with the large, blocky grip of the double-stack frame being uncomfortable for shooters with smaller hands, and its standard polymer sights, which are often the first component owners replace.¹¹ Despite these points, its overwhelming reputation for being an indestructible workhorse secures its position at the top of the market.

Smith & Wesson M&P 10mm M2.0

Launched in late 2021, the Smith & Wesson M&P 10mm M2.0 was a highly anticipated entry that immediately established itself as the Glock 20’s most significant challenger.¹ Smith & Wesson leveraged the success of its M&P M2.0 platform, directly addressing the Glock’s primary weaknesses to create a compelling alternative.

The M&P 10mm’s key strength is its superior ergonomics. It features the M&P line’s signature 18-degree grip angle, which many shooters find more natural than Glock’s more aggressive angle, and includes four interchangeable palm-swell backstraps to customize the fit to the user’s hand.¹³ The frame’s aggressive texturing provides a secure grip, essential for managing 10mm recoil. Internally, the polymer frame is reinforced with a rigid extended stainless-steel chassis, designed specifically to reduce frame flex and enhance durability under the stress of the 10mm cartridge.⁷

Reviewers consistently praise the M&P 10mm for its excellent factory trigger, which is widely considered superior to the standard Glock trigger, and its optics-mounting system, which ships with a full suite of adapter plates for a wide variety of red dots.¹¹ By offering superior ergonomics and a better out-of-the-box trigger at a competitive price point, the M&P 10mm has rapidly captured significant market share from consumers who appreciate the Glock concept but desire more refinement.

Glock 40 MOS

The Glock 40 MOS (Modular Optic System) is Glock’s purpose-built handgun hunting platform. It takes the proven G20 frame and pairs it with a long slide and a 6-inch barrel.¹ This configuration offers several distinct advantages for hunters. The longer barrel increases muzzle velocity, extracting maximum performance and energy from the 10mm cartridge, which translates to a flatter trajectory and more effective terminal ballistics on game. The extended slide provides a longer sight radius, which inherently improves practical accuracy with iron sights.

However, the key feature is the MOS cut in the slide, which allows for the easy mounting of a red dot sight.¹⁴ This is a critical feature for handgun hunters, as a red dot allows for more precise aiming at extended ranges compared to traditional iron sights, increasing the effective and ethical range of the firearm.⁹ The combination of the G20’s legendary reliability, the ballistic advantages of the long slide, and its optics-ready nature has made the G40 MOS the dominant choice in the semi-automatic handgun hunting market.¹⁵

SIG Sauer P320-XTEN

The SIG Sauer P320-XTEN is a testament to the modularity of the P320 platform and a direct appeal to the enthusiast market. SIG Sauer scaled up its P320 system to accommodate the 10mm cartridge, focusing on two key areas: ergonomics and recoil management.¹⁶ The XTEN utilizes the X-series grip module, which is widely praised for being more comfortable and less “blocky” than the Glock 20’s grip, making the high-capacity 10mm accessible to a wider range of hand sizes.¹⁰

Its standout feature, particularly in compensated models, is its remarkably soft-shooting nature. The combination of the grip ergonomics, slide mass, and (in some models) an integrated expansion chamber compensator makes the recoil impulse feel significantly tamer than its competitors, often compared to shooting a 9mm +P rather than a full-power 10mm.¹⁰ This appeals strongly to shooters who are recoil-sensitive or who prioritize rapid follow-up shots. The P320’s removable Fire Control Unit (FCU) also offers a degree of modularity not found elsewhere. The primary criticism involves its direct-mount optics system, which, while robust, limits the user to SIG Sauer or Leupold DeltaPoint Pro footprints without adapter plates.¹⁰

Springfield Armory XD-M Elite

The Springfield Armory XD-M Elite series has built a reputation for offering a high level of performance and features at a very competitive price, and the 10mm models are no exception. The XD-M Elite is positioned as a direct competitor to both the Glock 20 and S&W M&P 10mm, appealing to shooters who want a “fully upgraded” pistol from the factory.

Its key selling point is the Match Enhanced Trigger Assembly (META), which provides a flat-faced trigger with a clean break and short reset that is among the best in the striker-fired class.¹¹ It also boasts a standard capacity of 16+1 rounds, a slight edge over the 15-round standard of its main competitors. Other features like an ambidextrous magazine release, a grip safety, and aggressive slide serrations round out a package that feels premium.¹⁷ The platform’s durability is well-documented, with Springfield having subjected an XD-M 10mm to a 10,000-round torture test with no malfunctions.¹⁷ This combination of a superb trigger, high capacity, and proven reliability makes it a formidable option in the polymer-framed segment.

FN 510 Tactical

The FN 510 Tactical is one of the newest major entries into the 10mm market and is positioned as a premium, “no-compromise” tactical pistol.⁵ Based on the successful FN 509 platform, it brings a host of high-end features to the table. Its most notable feature is its class-leading magazine capacity, shipping with both a standard 15-round magazine and an extended 22-round magazine.¹⁶

The “Tactical” designation is well-earned. The pistol comes standard with a 4.71-inch threaded barrel for mounting suppressors or compensators, suppressor-height tritium night sights, and FN’s highly regarded low-profile optics mounting system, which uses a series of plates and inserts to provide a secure, co-witnessing fit for a wide range of red dots.¹⁸ The ergonomics are excellent, and the controls are fully ambidextrous. The FN 510 Tactical appeals to the enthusiast who wants a complete, mission-ready package right out of the box without the need for any aftermarket upgrades. Its primary drawback is its higher price point compared to its main competitors.

Glock 29

The Glock 29 has long dominated the subcompact 10mm niche, offering the full power of the cartridge in a package small enough for concealed carry.¹ It is essentially a scaled-down Glock 20, sharing its reputation for absolute reliability and durability.¹⁹ For individuals seeking a potent defensive firearm for either urban or backcountry environments where concealability is a factor, the G29 is often the only viable choice. It can also accept the larger 15-round magazines from the G20, offering increased capacity and a fuller grip when needed.¹⁰

The trade-offs, however, are significant. The combination of a powerful cartridge in a small, lightweight pistol results in a substantial and challenging recoil impulse that requires significant practice to master.²¹ The short grip provides little purchase for the shooter’s pinky finger, which can exacerbate control issues, though aftermarket magazine extensions can mitigate this. Despite the sharp recoil, its unique position as a reliable, concealable 10mm powerhouse ensures its continued popularity.¹⁹

Author’s backpacking pistol is a Glock 29 with Pierce magazine extensions for a better grip. Heavy loads from Underwood and Buffalo Bore are not a problem to control.

The Enduring Legend: The 1911 Platform

Despite the dominance of polymer-framed pistols, the M1911 platform maintains a deep and enduring appeal for 10mm shooters. This century-old design, championed by Jeff Cooper himself, offers an unparalleled trigger, excellent ergonomics for many shooters, and a timeless aesthetic. The market for 10mm 1911s is robust, catering to a wide spectrum of consumers from those seeking a premium, specialized hunting sidearm to those wanting an affordable, classic “big bore” plinker.

The single-action trigger of the 1911 is its most significant advantage in the 10mm space. For applications that demand the utmost mechanical accuracy, such as handgun hunting, the crisp, clean break of a good 1911 trigger is considered superior to any striker-fired or DA/SA alternative.¹⁰ This has led to a market bifurcation. At the high end, manufacturers like Dan Wesson produce specialized long-slide models purpose-built for hunters who prioritize precision over capacity. At the other end, companies like Rock Island Armory offer accessible, feature-rich models that allow a broader range of enthusiasts to experience the classic combination of the 1911 platform and the powerful 10mm cartridge.

Colt Delta Elite

The Colt Delta Elite is more than just a firearm; it is a cultural icon. Introduced in 1987, it was the first 10mm pistol offered by a major manufacturer and is widely credited with saving the cartridge from commercial extinction following the failure of the Bren Ten.³ For many years, the Delta Elite

was the 10mm market. Its popularity is deeply rooted in this historical significance and the power of the Colt brand.

Early models developed a reputation for being hard on their frames, with some instances of cracking due to the powerful cartridge.⁹ However, modern production Delta Elites have been significantly updated to address these issues. Key improvements include a dual recoil spring assembly to better absorb energy and protect the frame, an improved beavertail grip safety, and Novak sights.²³ While it may lack some of the modern features of its competitors, its legacy, classic aesthetics, and the simple fact that it is the “original” 10mm 1911 give it a market position that transcends specifications alone.

Dan Wesson Bruin / Kodiak

Dan Wesson, a subsidiary of CZ-USA, occupies the premium tier of the production 1911 market. Their 10mm offerings, particularly the long-slide Bruin and Kodiak models, are purpose-built for the handgun hunter. These pistols feature 6-inch barrels, which maximize the velocity and energy of the 10mm cartridge while also providing a long sight radius for enhanced precision.²²

These models are lauded for their exceptional build quality, featuring forged frames and slides with no metal injection molded (MIM) parts, a key selling point for discerning buyers.²⁵ The fit and finish are meticulous, resulting in a smooth action and superb accuracy. Features like adjustable night sights, front strap checkering, and premium G10 grips are standard. The Dan Wesson line appeals to the serious hunter or enthusiast who is willing to pay a premium for top-tier craftsmanship and performance tailored specifically for the field.

The Dan Wesson Bruin is a remarkable pistol to say the least.

Kimber Rapide Series

Kimber holds a significant share of the mid-to-high-end 1911 market, and their extensive 10mm lineup is a major contributor to this. Kimber’s strategy focuses on offering a wide variety of models with distinctive, “custom-style” aesthetics at production prices. The Rapide series, with its aggressive slide lightening cuts, stepped cocking serrations, and unique grip patterns, is a prime example of this approach.²⁶

These firearms appeal to the buyer who values visual appeal as much as performance. They come well-appointed from the factory with features like tritium night sights, G10 grips, and high-quality finishes. While Kimber faced some criticism in the past regarding quality control, modern production is generally held in high regard, and the brand’s strong market presence and vast product catalog ensure its popularity among 10mm 1911 enthusiasts.²⁷

Springfield Armory Ronin 1911

Springfield Armory offers a range of 10mm 1911s that effectively bridge the gap between the value-oriented offerings of Rock Island Armory and the premium models from Dan Wesson. The Springfield Armory Ronin is a particularly popular model that emphasizes classic styling and solid performance at an accessible price point.

The Ronin features a two-tone finish, with a stainless steel frame and a blued carbon steel slide. It eschews some of the more “tactical” features like an accessory rail for a cleaner, more traditional look. It comes standard with quality components like a forged frame and slide, a match-grade barrel, and fiber optic front sights.²⁸ The Ronin appeals to the traditionalist who wants a well-built, reliable 10mm 1911 without the expense of higher-end models or the aggressive styling of many tactical offerings.

Rock Island Armory TAC Ultra / Rock Ultra

Rock Island Armory (RIA), manufactured by Armscor, is the undisputed value leader in the 1911 market. Their TAC Ultra and Rock Ultra series pistols in 10mm deliver a feature set that is unheard of at their price point. These models typically include a full-length guide rod, an adjustable rear sight, a high-visibility fiber optic front sight, a skeletonized hammer and trigger, an extended beavertail, ambidextrous safeties, and aggressive G10 grips.²⁹

RIA has made the 10mm 1911 platform accessible to a vast segment of the market that would otherwise be priced out. While the fit and finish may not match that of a pistol costing three times as much, they have earned a strong reputation for ruggedness and reliability.²⁹ For the budget-conscious enthusiast or someone looking for a solid “base gun” for a custom project, the value proposition of the RIA 10mm 1911 is impossible to ignore.

This is the whole Rock Island Armory 10mm double stack 1911 family. On the bottom left is the 6″ 52000 Rock Ultra – sometimes called The Big Rock – with Turner wood panels. In the middle is the 52009 Rock Ultra HC, To the far right is the 56862 Tal Ultra HC Threaded.

The Force Multipliers: Pistol-Caliber Carbines (PCCs)

The pistol-caliber carbine segment is one of the most dynamic and fastest-growing areas of the 10mm market. A PCC platform unleashes the full ballistic potential of the 10mm cartridge; the longer barrel (typically 8 to 16 inches) can increase muzzle velocity by 150-300 fps over a handgun, resulting in a significant boost in energy and a much flatter trajectory.³⁰ This makes the 10mm PCC a formidable tool for home defense, tactical applications, and hunting small to medium-sized game.

A critical factor enabling this segment’s growth is the near-universal adoption of the Glock magazine pattern. Leading manufacturers like CMMG, Kriss, and Ruger have all designed their 10mm PCCs to feed from Glock 20/40 magazines.³¹ This creates a powerful ecosystem effect. A consumer who already owns a Glock 20 has a ready supply of magazines, dramatically lowering the cost and logistical barrier to purchasing a companion carbine. This cross-platform compatibility has made Glock magazine acceptance a near-mandatory feature for success in the 10mm PCC market and will likely stifle any new entry that attempts to introduce a proprietary magazine.

CMMG Banshee Mk10

The CMMG Banshee Mk10 is widely regarded as the top-tier, AR-pattern 10mm PCC. Its defining feature is CMMG’s innovative Radial Delayed Blowback operating system.³⁰ Unlike simple blowback systems used in many PCCs, which require a heavy bolt and buffer to safely manage pressure, the Radial Delayed system uses a rotating bolt that momentarily delays the rearward travel of the bolt carrier group. This allows chamber pressures to drop, resulting in a significantly lighter bolt and buffer, and most importantly, a dramatic reduction in felt recoil and muzzle rise.³⁰

The result is an exceptionally smooth and flat-shooting carbine that makes the powerful 10mm cartridge remarkably controllable. The Banshee also features a last-round bolt hold-open, full ambidextrous controls, and a high-quality fit and finish. Its use of Glock magazines and its superior operating system make it the premium choice for serious enthusiasts.³⁰

Kriss Vector Gen II

The Kriss Vector is famous for its futuristic aesthetic and its unique Super V System, a non-linear, multilink, delayed blowback operating system that redirects recoil energy down and away from the shooter’s shoulder.³⁴ This results in an extremely low bore axis and negligible muzzle climb, making the Vector one of the softest-shooting and fastest-firing PCCs on the market.³⁴

In 10mm, the Super V system effectively tames the cartridge’s stout recoil, making it feel more like a 9mm carbine.³⁵ Like the Banshee, it feeds from Glock magazines and is a favorite among tactical shooters and enthusiasts who appreciate its unique engineering and distinctive appearance. Its primary drawbacks are its higher price and unconventional ergonomics, which can take some getting used to.

Ruger LC Carbine

Ruger’s entry into the 10mm PCC market with the LC Carbine was met with significant positive reception. Leveraging the design of their successful Ruger-5.7 pistol and carbine, the 10mm LC Carbine offers a lightweight, reliable, and versatile package at a moderate price point.³⁶

Key features include a folding, adjustable stock, a threaded barrel, and a full-length Picatinny rail for optics. It utilizes a simple and reliable blowback action and, crucially, feeds from Glock-pattern magazines.³² Its lightweight and foldable design make it an excellent choice for a “truck gun” or a compact backcountry carbine. The Ruger LC Carbine successfully occupies the middle ground of the market, offering a significant step up in quality and features from the budget options without the premium price of a CMMG or Kriss.

Hi-Point 1095TS

The Hi-Point 1095TS holds its place in the market for one simple reason: extreme affordability. It provides a functional and reliable 10mm carbine at a price that is often less than one-third of its nearest competitors.³¹ While it lacks the refinement, advanced features, and ergonomic comfort of other PCCs, it delivers on its core promise of a durable, American-made carbine that fires the 10mm cartridge.

It uses a simple blowback action and is known for being surprisingly durable, often carrying a lifetime, no-questions-asked warranty. Its primary weaknesses are its proprietary single-stack 10-round magazines, which are low-capacity and less reliable than Glock magazines, and its heavy, bulky, and often criticized aesthetics. Despite these flaws, its ultra-low price point makes the 10mm PCC category accessible to virtually any consumer.

Classic Designs & Niche Stalwarts: DA/SA and Revolvers

While the market is dominated by striker-fired and 1911-style pistols, a dedicated niche exists for firearms with more traditional actions. This segment caters to shooters who prefer the deliberate double-action first-shot pull of a DA/SA semi-automatic or the ultimate simplicity and reliability of a revolver. These firearms often appeal to experienced shooters and hunters who value specific mechanical attributes over raw capacity.

SIG Sauer P220 Legion (DA/SA & SAO)

The SIG Sauer P220 has a legendary reputation for accuracy and reliability, and the 10mm version builds upon this legacy. Unlike the polymer-framed P320-XTEN, the P220 is an all-metal pistol, with most models featuring a heavy stainless steel frame and slide.³⁷ This substantial weight (often exceeding 44 ounces) makes the P220 an exceptionally soft-shooting 10mm handgun, absorbing a great deal of the recoil impulse.³⁷

Available in both traditional DA/SA and SAO (single-action only) configurations, the P220 Legion models represent the pinnacle of the line, featuring an enhanced trigger, aggressive G10 grips, and superior sights. The P220 appeals to the enthusiast who appreciates the craftsmanship of an all-steel, hammer-fired pistol and is willing to trade high capacity (it uses single-stack 8-round magazines) and light weight for a supremely smooth and accurate shooting experience.

Ruger GP100 Match Champion & Smith & Wesson Model 610

The re-introduction of 10mm revolvers by major manufacturers like Ruger and Smith & Wesson speaks to the cartridge’s growing popularity in the hunting and outdoor communities. The Ruger GP100 Match Champion and the S&W Model 610 are robust, N-frame-sized revolvers that offer a unique set of advantages.¹

Their primary strength is absolute reliability. A revolver is immune to the ammunition sensitivity that can sometimes affect semi-automatics; it will fire everything from very light “FBI Lite” loads to the heaviest, hard-cast bear loads with equal reliability.¹⁰ This makes them an extremely dependable choice for backcountry defense. A significant secondary advantage is the ability to also fire the less expensive and lighter-recoiling.40 S&W cartridge for practice, using the same moon clips required for the rimless 10mm Auto case.¹ Their main disadvantages are their limited 6-round capacity and slower reload speed compared to a semi-automatic. These revolvers appeal to traditionalists and those who prioritize the ultimate in reliability and ammunition versatility for a hunting or trail sidearm.

Market Synthesis & Future Outlook

The comprehensive analysis of the U.S. 10mm Auto market reveals a cartridge that has not only survived but is now thriving by finding its true identity outside of its original law enforcement design parameters. Having successfully navigated a near-death experience in the 1990s, the 10mm has been reborn, propelled by a confluence of cultural mystique, consumer demand for higher performance, and critical advancements in firearms technology.

The 10mm Auto has definitively established itself as the new standard for outdoorsmen seeking a semi-automatic sidearm for backcountry defense and handgun hunting. It offers a superior solution to the traditional large-caliber magnum revolver, providing a significant increase in capacity, faster reloading capabilities, and a more modern, adaptable platform—all while delivering comparable terminal ballistics to the.41 Magnum.⁹ The market dominance of firearms like the Glock 20 and Smith & Wesson M&P 10mm in this role is a clear indicator of this paradigm shift. Consumers venturing into areas with potentially dangerous game are no longer limited to a six-shot revolver; they now have the option of a reliable semi-automatic with 15+1 rounds of potent, deep-penetrating ammunition.²

This mainstream acceptance would not have been possible without the catalyst of technological accessibility. The punishing recoil that led the FBI to abandon the full-power 10mm has been substantially tamed by modern engineering. Polymer frames with carefully designed ergonomics, internal steel chassis to absorb stress, and advanced recoil mitigation systems like those found in the SIG P320-XTEN and CMMG Banshee have made the cartridge manageable and even pleasant to shoot for a much broader audience.⁶ Furthermore, the now-standard inclusion of optics-ready slides has unlocked the cartridge’s long-range potential, particularly for hunters, solidifying its role as a precision tool.

Looking forward, several trends are likely to shape the 10mm market’s future. The pistol-caliber carbine segment is poised for continued and significant growth. As more shooters experience the dramatic increase in performance and controllability that a carbine platform offers, demand for models like the CMMG Banshee and Ruger LC Carbine will intensify. This platform truly maximizes the 10mm’s velocity and effective range, transforming it into a viable short-range rifle for defense and hunting. Competition in the polymer-framed handgun space will also continue to heat up, with new manufacturers likely to enter the market, further driving innovation in ergonomics and recoil reduction. Finally, as engineering continues to evolve, the development of more reliable and shootable compact or even “micro” 10mm pistols could emerge, further expanding the cartridge’s viability for concealed carry.

In conclusion, the 10mm Auto has successfully completed its transition from a niche, enthusiast-only cartridge to a multi-faceted commercial success with a secure and expanding market. Its future is firmly anchored by its undisputed performance as a premier hunting and wilderness defense caliber, while its legendary power and unique history will continue to fuel its enduring appeal to the serious firearms enthusiast.

3. Expert & Influencer Reviews (20% weight): This metric captures the consensus from established, trusted sources within the firearms industry. The analysis includes a systematic review of published evaluations from leading print publications (e.g., American Rifleman, Guns & Ammo, Handguns Magazine) and influential, high-reach digital media channels (e.g., Hickok45, Gun University, Pew Pew Tactical). The focus is on identifying points of consensus regarding a firearm’s reliability, accuracy, ergonomics, and performance with a variety of ammunition loads under controlled testing conditions. This provides an essential layer of professional validation to the user-generated data. ¹¹

4. Cultural Relevance (10% weight): This qualitative metric acts as a “popularity multiplier” to account for a firearm’s intangible mindshare and historical significance, which can drive long-term market presence beyond immediate sales figures or technical specifications. A model’s score is increased based on its status as a cultural icon (e.g., the Colt Delta Elite’s role in saving the 10mm cartridge) or its establishment as the definitive, go-to choice for a specific, high-profile application (e.g., the Glock 20’s reputation as the premier bear defense handgun). This factor acknowledges that a firearm’s story and reputation are integral components of its market popularity. ³

Data from each of these four sources is compiled and normalized to a common scale. The weighted average is then calculated to produce a final composite score, which determines the firearm’s rank in the Top 20 list.

Disclaimer: The rankings presented in this report reflect market popularity as determined by the proprietary methodology described above at the time of its creation. They are not a direct endorsement of any specific product or a definitive measure of absolute quality, but rather an analytical snapshot of the U.S. 10mm Auto firearms market.

Stribog SP10A3 10mm At The Range

September 2, 2024 RoninsGrips

I posted about the modifications to the SP10A3 as well as magazine loaders and now it is time to talk about how it performed. One of my brother-in-laws and nephews were in town and ready to help me try it out. First off, we had a lot of fun and second, the 10mm Stribog ran stunningly well.

Preparing For the Range

When the Stribog arrived, I field stripped, cleaned and lubricated it. This is always a good idea because you never know what all will be in a firearm – preservatives, dirt or even dry with no lubricant.

The manual is well written so read it. The sections on field stripping, cleaning, and oiling are worth your time. I would also recommend hand cycling the action a few hundred times to accelerate your parts getting to know each other – also known as wearing in.

The bolt assembly made up of the large carrier to the rear (right) and the bolt head in front (left), is enormous. A lot of the 10mm recoil is eaten up by inertia, the recoil spring and then a giant buffer block. It’s no wonder the recoil is incredibly mild. Also, when you have something this big, there can be a ton of friction so you need to lubricate it.

This giant rubbery green thing is the recoil buffer. I honestly don’t recall ever seeing one this big – every. If the inertia of the bolt and recoil spring leave enough energy to drive the bolt carrier into this buffer, it can handle it without a doubt.

Visiting the Range

My brother-in-law, Banduy, and nephew, Julian, headed to the range to have some fun and break in the Stribog. It was a great day as we unloaded and set up the targets, moved the bench into place and got ready.

We used the Custom Smith .45 UMP loader to fill up four 20 round magazines with S&B 180gr FMJ. Folks, I have shot cases of this stuff and it’s fantastic range ammo in all of my 10mm pistols and now the Stribog.

I shot the first magazine and was very impressed. The action was smooth with very little felt recoil. I did need to dial in the UH-1 a bit as the laser boresight allowed me to get the UH-1 in the vacinity if the round impacts on the paper.

By the way, I initially had a quick connect sling loop on the A3 Stribog adapter just about the top rear of the grip. It was really annoying and I got rid of it very quickly. Maybe someone with smaller hands wouldn’t notice it but I sure did.

Julian has been shooting with me for almost 20 years now. Time flies by. He was next up and with practiced skill did a steady 20 round set standing freehand with no problems at all.

This was his first 20 round set as he got used to the Stribog. He was about 25-40 feet back getting started.

I haven’t done a comparison of felt recoil with the micro compensator and without. I can tell you that it is incredibly smooth with it on.

We had a lot of fun. The Stribog just rocked it, No failures of any kind through 200 rounds of ammo. The one thing I realized after the outing was that I could shoot through a case of 10mm pretty quick with the SP10A3.

Summary

We shot the Strbog freehand back to about 25 yards and found it to be a delight to shoot. It definitely filled my desire for a 10mm carbine vs. my various 10mm pistols and would highly recommend it. GrandPower did another great job with the SP10A3.

I’ve since had it out a couple of more times and it’s run great everytime. Yes, I did have to buy more S&B 180gr ammo because of it 🙂

I hope this helps you out.

Note, I have to buy all of my parts – nothing here was paid for by sponsors, etc. I do make a small amount if you click on an ad and buy something but that is it. You’re getting my real opinion on stuff.

Why you need to clean, lube and break in Rock Island Armory Pistols

March 16, 2024 RoninsGrips

As some of you may know, we make custom magazines for the Armscor Rock Island Armory (RIA) A2 HC family of .40 and 10mm pistols. Once in a while I get to talk to a new owner before they go to the range and either they ask for advice or I give it regardlesss 🙂 I will tell anyone that will listen that they need to clean, lubricate and cycle their pistols 200 times before they go to the range. I’ve been sharing this advice for years but never really had evidence. Guess what? Now I do and I truly hope people will take this to heart and do it.

I recently purchased a RIA 52000 Big Rock – this is their 6″ barrelled 10mm match pistol. I had one years ago that I sold when I needed money and regretted it – especially after I started making the custom mags. What I am going to show you is true of all Rock Island 1911-style pistols – not just the A2 HC models – and for almost all semi-automatic factory-produced firearms. They are not ready to go out of the box and if you take them straight to the range they are going to fail a lot, you’re going to get frustrated, blame the gun/ammo/mag/dealer and it’s not their fault so please read the following and heed the advice.

Opening the Factory Box

For RIA 1911 pistols, they ship them in a bag absolutely coated in some kind of oil – just what I am not sure. Do not look at that and think it is all lubricated and ready to go. It absolutely is not and it is actually pretty dirty – you need to get rid of all of that including the junk in the bore.

STOP is right. What is in the bag is not ready to go.

First off, wipe it down. It will be drenched in oil to keep it from rusting. The 52000 Big Rock is definitely big.

This is what your white towel will look like. Note it is not just clean oil – there is debris in it and it’s not inteded to lubricate but to prevent rust. This stuff is everywhere in the pistol and we need to field strip the pistol, clean and oil it to ensure proper functioning.

Now you may be thinking your Glock was pristine compared to that and while it was cleaner it was also pretty dry and needed to be lubricated. The Rock Islands are decent but they need to be cleaned up.

How about the barrel?

The anti-corrosion “oil” and grime are everywhere in the pistol.

This is a real photo of an area of the bore before cleaning. It was captured with my Teslong borescope. The brass or copper color is probably from the test firing they did but the main thing for you to see is all of the preservative and grime in there, You do not want to shoot with this junk in there as it could adversely affect the pistol in any number of ways including affecting accuracy, By the way, the Teslong Rigid Rifle Borescope with 1080P resolution is pretty remarkable. I really like mine – it’s many times better than anything I have experimented with that I could afford.

I have used Ramrodz for years – the giant Q-tips on the right – to clean pistols. I just started trying the Clenzoil Bore Stix (on the left) and they seem to be decent with the advantage of having a cleaner/lubricant on them already. The Ramrodz being unprepared let me decide what I want to coat them with given the situation at hand so pros and cons with both. BTW- the sticks can snap easily so you hold them close up by the “bulb” when you insert them and then run the back and forth with the stick.

Here’s what the first Ramrodz looked like after I ran it up and down the bore a few times. It was coated with Kroil penetrating oil to help break things free. You can see the grime that came out.

I then decided to try a Bore Stix with just its normal coating.

The Clenzoil BoreStix seemed to remove even more grime than the Ramrodz but it is hard to say because the Kroil was in there working as I switched from the RamRodz to the Bore Stix.

This is after cleaning and lubricating. Again, the Teslong borescope is a game changer for me in terms of actually seeing the bore in considerable detail.

What I want you to take away from this section is to clean the bore – you can absolutely use your favorite method – patches, boresnake, whatever – but definitely clean it.

Field Stripping the Pistol

Armscor includes a half-way decent manual about how to field-strip your 1911 and I recommend you read it. Some of their models have barrel bushings and they have at least two models of full length guide rods that I know of. You just need to break the pistol down into its major groups – do not start taking apart the frame unless you seriously know what you are doing or you are going to get a hard lesson in how a 1911 goes together internally and it is not simple enough for the average shooter in my honest opinion. If you are a person that assembles 1911s from the bare frame – go ahead and do it. Have fun. If you have never disassembled and reassembled a 1911 – don’t. You don’t have to at this point is the bottom line.

One unique thing about the Big Rock you need to know is the unique full length guide rod (FLGR) they used and as far as I know, it is not in any other RIA pistol. If you have one of the 10mms, you are aware of the FLGR design which uses a pin to capture the two halves of the FLGR from separating, The Big Rock’s FLGR is threaded. To remove it, you turn counter-clockwise quite a few turns to unscrew the two halves and separate them. Now pay attention – that is a 20 pound spring in there and it will launch one half or the other so capture or retain the assembly by securing it with your other hand to prevent you from digging around for a launched part.

That slotted part is the FLGR and it is removed by turning it counter clockwise. I was taking pictures here – remove it with the slide closed so there is less tension on the spring. Notice the dent in the outer edge of the barrek at about the 5 o-clock position. The crown was fine and that’s what really matters. I’m not going to bother sending it back.

I’m not going to write a comprehensive guide to lubricating a 1911, read your pistol’s manual. I will tell you I now use ALG’s Go-Juice which is a thin grease on anything that slides. Before the ALG, I used Super Lube Synthetic Grease applied with an acid brush and before that I used wheel bearing grease. I would at least recommend doing this while the weapon breaks in. If you want to go to an oil later after it has worn in, then do it by all means. Right now though, you need the extra lubrication the grease brings. If surfaces slide together, use grease.

If they turn, use oil. I am all over the place trying oils. Right now, I am using ALG’s biosynthetic stuff. Don’t ask me what is in it. Before that I have used a ton of different oils – MGW, Super Lube, Mobil 1, etc., etc., etc.

Getting a jump on breaking in the pistol

You will hear guys call it “breaking in”, “wearing in”, “letting the parts get to know each other” – they all refer to any firearm needing to smooth out parts through their normal cycling. Expensive guns, such as customs and semi-customs, an experienced gunsmith used huning stones, rubberize abrasive bits or whatever was their preffered tool, to get rid of the tooling marks and sharp edges to give you a smooth weapon right out of the box.

Well, RIA is not expensive and they don’t spend a ton of time fitting and tuning their parts for a perfect fit. You know what? I’m fine with that – it’s easy to smooth things out but first I want to show you why you need to do this via some digital photos courtesy of an Andonstar AD246S-M digital microscope.

The following are example photos showing the tooling marks on various areas that need to slide freely. The tooling marks are everywhere and cause friction until the places where surfaces contact start to wear down the protruding areas:

Sample of tooling marks on slide rail area

Tooling marks on the receiver’s slide area.

Front of the left side of the receiver – the shiny areas are already making contact with the slide and wearing in.

Again, the above are all examples. Areas starting to shine are wearing in and starting to smooth out. I’d maybe cycled the slide a dozes or so times before the above photos were taken as I wanted to show before.

Now, there are tons of things you could do with honing storines, rubberized abrasive bits and even with lapping stones. If you want to do one or more of those, go for it. I have an even simpler solution – rack the slide open and closed a couple hundred times. Literally, don’t have a mag in it and work it back and forth over and over. It’s a workout with that 20# spring but it will accelerate wear-in dramatically. Think about it, a lot of firearms get more reliable just under a 100 rounds. You are really smoothing things out at 200, What you will notice is that if you do the above, you will not waste a lot of time and money dealing with jams.

How do I know this? I have owned a number of RIA pistols over the years. My test pistols that I use to test each mag before they leave have been handcycled thousands of times and the slide feels like that of a high-end pistol – like it is sliding on glass.

The following photos show contact areas after thousands of cycles:

Shiny areas neans the parts wore together and smoothed out.

In this area the tooling marks are all but gone.

Again, lots of wear – only the deepest tooling marks are still there.

Guys are always surprised how smooth these pistols are and then even more surprised when I tell them they are unmodified RIA pistols that have had their slides cycled thousands of times.

So, do you need thousands of times? No, just go for 200 and you can do more if you really want to.

Last comment on the FLGR and reassembling it

I seriously started hating on the unique Big Rock FLGR design when it came time to put it back together. You are fighting a 20# spring and I couldn’t remember how I did my last one years ago or find any tips or tricks about how to do it. The best thing I can tell you is that you need to secure the back half against the barrel link with the left hand. Insert the front section with the right and try to get front threaded insert into the hood of the back, try to hold them in approximate alignment as you try to screw the front half back in. Translation – it sucks and I have no tips.

I haven’t gotten this frustrated iin a while. The FLGR assembly is those three parts – the 20# spring and the two sliver rods. The one saving grace, the only saving grace for that matter, is the design of how they come together. The two shafts need to line up with the front long part with the slot sliding into the short stubby back part hat has a hooded opening.

This photo was mere seconds before I launched the back half six feet away where it luckily hit a wall and dropped in plain sight because I wasn’t keeping it secure enough with my left hand. Note, I still have a 1911 recoil spring plug somewhere that launched in my shop and was never found.

This is just to prove it is possible to get them back together. Note the purple ALG thin grease on the slide.

Summary

I hope this post helps impress on you the need to clean, lubricate and cycle your pistol, or whatever firearm, before you go to the range the first time. I do this myself and have shared it with many, many folks over the years and the feedback has always been positive.

By the way, the majority of guys who contact me hating on the RIA pistols did not break them in so I walk them through this. The second largest majority are really frustrated with the OEM magazine.

If you need mags for your 10mm or .40 RIA pistol (notably models 52009, 52682 or 52000 – also called the “A2” or “HC” series pistols (the big staggered 15-16 round models), please think of us. Our mags are far, far better than the OEM mags that come with the pistols – better springs, longer, antifriction coating and more.

What Magazine Loader To Use For 10mm Stribog Magazines? .45 UMP Loaders

February 10, 2024 RoninsGrips

The Stribog line of subguns, pistols and pistol caliber carbines are really cool. When the brace fiasco erupted, I sold my 9mm SP9A1 and regretted it. When Grand Power said they were coming out with a 10mm, I was an early buyer. One question popped out though – what was out there to help load the 20 round 10mm magazines? I hate loading magazines with stiff springs as many hands start to cramp so I needed to find a loader.

First off, they are HK UMP pattern magazines

The Stribog 10mm mags are nicely made, beefy as hell and based on HK’s UMP magazines. I like that – I am really tired or proprietary mags where you have one and only one option. Using an existing mags opens up options. Now, are UMP magazines all over the place and cheap? No, they aren’t – especially not 10mm mags. HK doesn’t make 10mm UMP magazines any longer.

The 20 round magazines have stout springs and it takes a lot of work to manually insert cartridges

Real HK 10mm mags have starting costs around $139 but are 30 rounds so there is a perk for the price. Considering Stribog mags list at $45 and can sometimes be found for $39.99, I’ll stick with Stribog mags.

Stribog 10mm magazines are built like a tank

This is both a pro and a con. The top sports a lot of reinforcements making for a quite a large magazine in terms of circumference. They will not fit inside a Maglula Universal loader – I had hoped they would but it is a no-go.

The girth of the heavily built mags means most loaders will not fit them. On the other hand, those are some impressive reinforcements on the mag lips and thick walls.

Distance from the botttom of the locking tab to the top of the magazine body is about 0.96-0.97. It’s molded so there’s a bit of ballparking as to the exact top.

The magazine locking tab is about 0.18″ thick.

Playing a hunch

Ok, so I did some searching on .40 caliber and 10mm UMP loaders and then played a hunch. I make magazines for Rock Island Armory’s A2 HC .40 and 10mm pistols. They use a staggered magazine and my source tube for the custom mags I make is actually a Mec-Gar .45 mag. What if a UMP .45 loader would work? I had a pretty good hunch it would so I started researching them.

The UMP .45 is much more common so I had options. The one that caught my eye was from Custom Smith so I ordered it and must say I am impressed.

It is 3D printed and nicey done. Everything seems thick enough to have proper rigidity. I like finger rests on the sides to give your hand something to get hold of. I promptly loaded two mags super easy. You push down, slide the cartridge in part way, lift the loader up, slide the cartidge in the rest of the way and repeat.

The ram that pushes the cartridges done is beefy and nicely done.

The ram does a great job pushing the last cartridge down so you can slide the base of the next cartridge part way in. You then move the loader out of the way, push the cartridge all of the way in and move on to the next round.

Summary

Grand Power Stribog’s 10mm model uses magazines based on the HK UMP design. The Grand Power magazines are affordable and relatively easy to find. You may need to dig just a bit as the 10mm Stribog sales are outpacing magazine availability but I am sure the mag availability will catch up.

To load the stiff magazines and save your fingers, get a UMP .45 loader. I went with Custom Smith’s UMP .45 loader and have no hesitation recommending it.

No, I wasn’t paid to write this – I had to buy it because I wanted the 10mm Stribog and manual mag loading kills my hands.

By the way, S&B 180 grain FMJ 10mm is my goto range ammo. It’s affordable and runs great. I use it for breaking in and target practice with all of my 10mms.

PSA Has A Great Deal On RIA 52009 HC 16 Round 10mm Pistols Going On – You Better Not Wait If You Want One

I haven’t seen these at this price in the last few years – PSA has them for $649.99. I suspect they will sell fast at that price.

I have one of these 52009 Ultra HC pistols and it is rock solid. Magazine customers tell me the same thing. If you’re looking for a double stack 10mm on the 1911 platform, this is a really good deal:

This is from a range visit last year. My RIA 52009 is at the bottom. The pistol on the top right is a 10mm TRP Operator. I still have the 52009 and like it but sold the TRP.

Do You Need 10mm or .40 S&W Magazines

We make custom high reliability magazines for the 10mm and .40 S&W RIA A2 HC pistols if you are interested. Click here for our store page.

This is one of our 3rd generation magazines. We start with a Mec-Gar P14 .45 magazine tube and modify it to hold both the 10mm and .40 S&W rounds. We have tons of satisfied clients using both calibers.

Conclusion

Just a short post today. That’s such a good price on the 52009 that I figured it warranted it and hope this helps you out.

Adjusting the the feed lip gap on our 3rd Generation RIA 10mm and .40 S&W Magazines

March 7, 2022 RoninsGrips

As you may know, we offer a third generation staggered 16 round magazine for Rock Island Armory (RIA) pistols chambered in either 10mm for .40 S&W. Having the correct front feed lip gap is critical for reliable feeding and I want to update you on some changes.

S&B 180gr FMJ round. The black “flaps” over the back of the cartride are known as the “feed lips”. They serve to limit how far the cartridge sticks up, the vertical angle as well as the left-to-right angle. On our magazines, it is the front of the lips, or right right edge of the lips in this photo, that are key for proper positioning of the round.

When I first started the magazines, I was setting the front edge of the feed lips between 0.36 and 0.375. In talking with customers who have bought the mags and were having feeding problems (notably stovepiping) , when the magazine lips were down at the lower end of 0.360″. I’d walk them through setting the gap for their pistol and at the end, I would have them measure the final front lip gap that worked. It was usually between 0.370 and 0.390″ and averaged 0.380″.

June 2024: The nominal front feed lip gap is 0.375 +/- 0.002. 0.380 seems to be the average maximum but the best average gap is that 0.373-0.377 range. Your pistol might vary so look at how the bullet points towards the chamber – either straight in or just slightly below. Some tinkering will help you figure out what is best for your pistol and the types of ammo you are shooting.

There are a lot of different 10mm cartrdiges on the market. Look at the different bullet shapes – the different angles can all affect reliable feeding which is one of many reasons why you may find one pistol likes one ammo and can cycle it all day long but not another.

Adjusting the Feed Lips Isn’t Hard

I’d recommend the following tools for the adjustments:

1/2-3/4 pound non-marring mallet – or even both. A lighter one for fine adjustments and a heavier one for coarse adjustments. It doesn’t take much to bend the lips. (May 2024 Update: I started using sheet metal hammers maybe a year and a half ago and find that they work great. The force of the strike bends the metal very nicely and doesn’t hurt the finish so while the photos all say use a non marring mallet – I would tell you to get some basic light sheet metal / body work hammers. Cheap ones break down quickly as the face of the hammer is weak so read reviews and get a good one. You just need a decent flat face and not a lot of weight – look at Martin, Fairmount, Performance Tool, etc.)
A pair of snap ring or malleable chandalier pliers that can spread the lips open. I highly recommend the Westinghouse 70099 pliers specifically because they have nice wide jaws that really help you make solid contact with the lips. Other brands have narrower jaws, probably to lower costs, that work but want to roll over on you while you are adjusting.
A pair of straight plastic jawed pliers come in hand if you need to tweak the lips left or right. I like the Beadsmith Parallel Pliers with nylon jaws for this work.
A vise with non-marring jaws or some means to hold the mag without crushing or excessive scratching
Digital calipers will help you with consistency and recording what gap your pistol works the best with give a particular type of ammo. Amazon has a ton of 6″ calipers so look at the reviews and decide. I use Mitutoyo 500-196-30 calipers but I need that level of precision and robustness due to constant use.
Use Zoom Snap Caps to test cycling vs live ammo. In general, snap caps or action proving rounds are a good idea to avoid misfires. There’s also a second reason – the recoil springs in the RIA pistols are robust and if the bullet from a live round or dummy round (a bullet loaded into a case that does not have powder or a primer) smacks hard into something, it will get pushed back further and further into the case plus they deform easily. All of my testing is done with solid aluminum snap caps now. I use A-Zoom 10mm Snap Caps for both my 10mm and .40 S&W mags. I’ve had positive feedback from owners of .40 S&W pistols so I know they work for both. Note I do NOT use A-Zoom snap caps for 9mm as the bullet shape does not remotely reflect common 115gr FMJ ammo at all.

From left to right bottom row: Vaughan 3/4 pound NT-125 mallet, Vaughan 1/2 pound NT-100 mallet and Westinghouse 7009900 lighting fixture chain pliers. The Vaughan mallets hold up great – the plastic is both pretty solid and robust so tapping in the feed lips goes very smoothly.

The Westinghouse pliers make opening the feed lips wider a very easy job. You could also use snap ring pliers but they will not distribute the pressure the same or be as easy to use.

The Westinghouse pliers have wide jaws – meaning left to right in the photo above. I’ve bought a number of chain pliers and the cheaper ones do not have as wide of jaws and have a tendency to want to roll when you are applying pressure. They work – but take a bit more control on your part.

Procedure to follow

Ensure your pistol is unloaded and no ammo is immediately nearby that might get accidentally loaded during testing.

Okay, let’s walk through the steps:

Checking Cartridge Alignment

Lock the slide open
Put a snap cap in the magazine
Insert the magazine into the pistol
From different angles, look at where the catridge is pointing in the chamber. Imagine a line from the center of the bullet going straight forward – where is it hitting? You will want to make small adjustments and test over and over until you get that bullet pointing into the center of the chamber (no, it does not need to be perfect).

The front edge of the feed lips are adjusted such that the cartridge is aiming into the middle of the chamber vertically and horiztontally.

Adjusting The Vertical Angle

On most mags, including our’s, the angle the bullet sits at is adjusted by changing the gap of the front mag lips. The back can’t be adjusted because it will buckle or crack given the right angle bend to the back. What happens is that by opening the front of the mag lips, the front of cartridge sits higher (meaning it is a steeper angle). Correspondingly, by narrowing the front of the mag lips, the cartridge can’t rise up as far and the bullet sits lower.

The circle representing a cartridge is the same size in both figures. By making the gap wider on the right, the circle rises up higher before it contacts the black feed lips.

The angle is often the biggest problem. If the bullet isn’t angled enough, it gets stripped from the magazine by the slide and will either slam straight into the feed ramp and stop or it will hit, shoot up at a 45 degree angle jamming the pistol open – this is known as “stovepiping”. In both of these cases, you would want to open the lips up until there is proper feeding.

There is such a thing as the lips being too wide and hitting the top of the chamber or literally falling out. The feed lips need to be narrower than the case diameter of 0.421″ for sure otherwise the case will literally fall right through the lips.

I set the lips at 0.375 +/- 0.002 and you will need to see what works best for your pistol and the type(s) of ammo you are shooting. You may find you need a couple of mags at one gap for the type of HP ammo you are shooting and a couple of mags for FMJ. Personally, my pistols run all of my S&B, Buffalo Bore and Underwood ammo with that 0.373-0.377 range.

To open the front of the lips, use the chain pliers shown above on the front of the feed lips. It doesn’t take much pressure to open (or close) the feed lips so you will need to get the “feel” for how much to squeeze.

To close the front of the lips, tap the left feed lip in and then the right feed lip in equal amounts using the mallet. If you aren’t careful then you are liable to have the bullet pointing too far left or right even though the gap is the same.

Note, it doesn’t take much force with the mallet to move the lips. If you go crazy and crush the lips such that the gap dips below 0.33″, you may find that the throat of the magazine bent and the follower will not longer be able to pass. You don’t want this to happen so make small adjustments, measure and test over and over.

Adjusting the Horizontal Angle

You have a few ways to adjust the left to right horizontal angle. The first is to tap the lips in the direction you need. You can hit in the outside edge of the lip to close it or the right side to open it. I don’t use this because I find it takes too long.

I like to use parallel plastic jawed pliers that fit right inside the lip and let me easily adjust the angle with a good deal of control.

Here’s another look at the lips without a cartridge present.

Here’s a magazine with a 180 grain FMJ round by S&B loaded.

It really helps to number your magazines so you can keep track of feed lip gaps, which ones are having problems, etc.

Summary

Each pistol can vary slightly so each magazine may need different feed lip gaps. Going forward, the feed lip gap on our 10mm and .40 S&W magazines will vary between 0.370 and 0.380″. This gives you a starting point but you may find a bit of final tweaking of the feed lips beneficial.

If you are reading this and are not using our magazines, your feed lip gap may differ.

I hope this helps you out.

Glocks, Self Defense

I Use A 5.11 Select Carry Pouch To Conceal Carry My Glock 29 Gen 4 When Hiking

January 25, 2022 RoninsGrips

I recently wrote about my Glock 29 Gen 4 and carrying it while hiking. A fellow asked me for more details on what I was using to carry it ands I told him I was using a 5.11 Select Carry Pouch – which is a fancier product name than “tactical fanny pack”. Joking aside, it really does a great job.

Ok, why the fanny pack? I’m on the heavy side and when I go hiking I am usually wearing shorts or sweatpants depending on the weather. Jeans are a “maybe” but I’m at the point in life where I go for comfort. I’m sure not dressing to impress anyone.

If I am wearing jeans and can use a pistol belt then I might use a holster but it depends on the weather. I’d rather conceal the firearm vs. dealing with people staring at my pistol as we are walking along. If I am wearing a coat or open long sleeve shirt then I might wear a belt holster. My preferred option is a Galco shoulder holster.

What I find is that I am often hiking or fishing and it’s too hot for a coat or loose shirt so I had to figure out what to do. I knew a fanny pack might look goofy but would work great if I could find the right one given how it could distribute the weight while concealling the pistol.

The Glock 29 gen 4 is relatively compact but it is not tiny by any means and once you load it down with 10 rounds of 10mm and have a couple of back up mags of 10mm, you’ve got a lot of weight to deal with.

A couple of years ago I ordered in some different models of the no-name import fanny packs that claim to support concealed carry and the quality was very disappointing – light fabrics, lousy sewing and poor zippers across the board. They weren’t an option for the Glock 29 gen 4 because they would never hold up to real world use.

There are a lot of carry options out there but I think I can make the blanket generalization that you get what you pay for – you need a well thought out design, rugged materials, a rock solid zipper and these aren’t cheap.

One company I like is 5.11. Their gear is reasonably priced and has never let me down. Yes, I am getting to my point – their 51804 Tactical Select Carry Pouch is very well made, looks good and doesn’t attract attention. It’s a tight fit but I can squeeze in my G29 with the Pearce magazine base plate so I have a place to rest my pinky finger, two more 10 round mags and a Streamlight TLR-8 that I keep in a side pouch.

The main pouch is a tight fit but I can squeeze in what I need. It’s symmetrical so you can insert the pistol facing either left or right. I have mine set up to rip open with the left and pull the pistol out with my right hand.

Here’s another angle. When you have the load shown, there is very little extra space.

I keep a TLR-8 stored in the right side pouch. It’s a snug fit also.

They call that thing sticking up a “hot pull strap” that you can use to yank the compartment open in a rush. Now that folks is one heck of a good idea. If you are in a hurry and the adrenaline is kicking in, fumbling with a zipper is going to suck. Grabbing that pull strap and yanking open the pouch is very do-able.

To give you an idea of real world sizing, a G29 Gen 4 is about 7″ long andjust over 4.5″ with a regular mag. Let’s just round that to 5″ in my case with the Pearce base plates. You can see in the photos that it is a snug fit. My Sig P365 fits no problem.

It works great for me. If you are interested, here’s the link to the pouch on Amazon – click here. Also, here are other sources for you:

Seeing The Different Dawson Precision Base Plates For Para P16 and RIA A2 HC 9mm and 10mm Double Stack Pistols

January 22, 2022 RoninsGrips

I genuinely like the Rock Island Armory (RIA) double stack 10mm pistols. I jumped into the deep end of the pool and started converting some really cool Mec-Gar Para P16 mags for use in the 10mm and .40 S&W pistols for folks who need either 10 or 15 round limited pistols due to unfortunate magazine limit laws where they live. The feed lips must be shortened and reprofiled to work reliably in RIA double stack pistols.

I’ve written about the conversion and you can click here to learn more but I didn’t really show a lot of photos of the different Dawson Precision base plate options. In addition to changing the feed lips, you have to replace the plate because it literally will not fit in the funnel – it’s a show stopper plus it really does need to be longer to allow for positive seating of the mag in the pistol. You could grind the OEM plate down but then you would need to glue/add material so you can fully set it – note, if you do that, leave a hole so you can unlock the plate in the future.

This post also applies to folks who own the RIA A2 HC double stack 9mm pistols. The same base plates are used on the magazines for your pistols as well and the magazine capacity is limited to 15 rounds as a result.

At any rate, here are a number of photos showing the Dawson Precision base plates and get a better idea of their different thicknesses relative to each other as well as when fully seated in the pistol:

The Dawson plates are machined from aluminum and their sizes are how much thicker they are than the original Para P16 base plate shown on the right. The bottom left Dawson plate is their +200 model and the one above it is the +300.

Here are the three Dawson plates next to each other on our converted P16 magazines. The +100 is on the left, +200 in the middle and +300 on the right. They increase the height and weight of the mag but do not increase the capacity.

With our 3rd Gen mags, Mec-Gar started using the left polymer plate and it works great in the RIA pistols. Both it and the +100 Dawson plate sit flush in the RIA mag funnel.

These 15 round windowed mags all have +100 Dawson plates.

This is a +100 Dawson plate in my RIA 52009 Ultra HC 10mm pistol.

This is the 3rd gen polymer Mec-Gar plate that comes on the 10mm/.40 S&W mags for reference. It fits the RIA funnel just fine.

I do need to note something – out of the two to three hundred converted P16 mags I sold, two buyers had pistols where the distance from the mag catch to the bottom of the funnel would not allow the mags with the Dawson plates to fully seat. I gave them full refunds and don’t know if the issue was the mag catch or the fitment of the funnel to the pistol. Again, only two gentlemen out of hundreds. I really do not think it was an issue with the base plates just to be clear – just stacked tolerances going in the wrong direction.

Summary

Dawson Precision makes great base plates for Para P16 and P18 magazines that enable them to fit in the funnel of most RIA high cap 9mm, 10mm and .40 S&W pistols. They come in three sizes and you can choose based on your preference.
