I sent out an email newsletter the other day with a photo of my RIA 51679 Tac Ultra in 9mm with wood grips. I also mentioned they are the only wood grips I have ever liked and was being honest. What surprised me was the number of people who emailed me asking if I had more photos and I do.
Mark Browne is the owner of Browne Works, Inc., located in Pasadena, MD, southeast of Baltimore. He has a wide variety of offerings for the Ultra and Tac Ultra both FS and MS models. He also has them for the A2 HC (like I needed) plus the BBR. The pricing is very reasonable also and he has a variety of materials you can choose from – click here for his website. If you want more info, I did a blog post about them a while back so click here for that to open in a new tab.
Otherwise, here are the new photos:
I hope you enjoyed the photos.
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.

One of the things I enjoy about the firearm industry is meeting neat people. Dan Barnett contacted me a few weeks back. He is a certified “polymer” pistol armorer and had recently got into 1911s. As part of the journey, he purchased a used Rock Island Armory 51679 Tac Ultra FS HC 9mm and was trying to sort out why it was failing to eject way more than he cared for and he would have an empty case and a round trying to be fed in the slide at the same time. He and I hit it off because we both like the soft shooting Rocks.
Because of my past experiences with RIA Tac Ultra 9mm extractors failing, I asked him how his looked and he told me that it looked nice and sharp – no broken parts. I send him my blog post on extractors and recommended he switch his to a Wilson Combat if he ever runs into a problem or wants to make the upgrade anyways.
There was a possibility the extractor tension was too light but I figured we’d assume it was okay for the moment. Note, if you open a slide slowly and watch the cartridge or casing being extracted, the extractor should maintain control all the way to the ejector. If it doesn’t and the extractor looks ok then it is most likely the tension and there are specialty gauges out there for testing and setting them.
With the extractor tentatively ruled out, what I told him was that not many people understand how critical the magazine feed lips are to proper feeding and ejection of a 1911 and that his Tac Ultra was just that – an oversize 1911.
What can happen is that the front feed lip gap can be set too wide allowing the front of the cartridge to tilt up in the air too far. Then, as the newly extracted case comes backwards, the riding too high bullet pushes the spent case up just enough to miss the ejector. Honestly, there is a really delicate brilliant dance going on inside a 1911 and all it takes is something to be off just enough and things go wrong.
Dan took his calipers to the four mags he had and the front of the feed lips that can be adjusted were all over 0.320″ and I recommend starting somewhere between 0.308 to 0.312″. There isn’t a magic number due to all of the variables one can encounter. Too wide and it can cause a failure to eject or stove piping. You can even have rounds falling out of the mag. Too narrow and you have the cartridge moving straight ahead, smashing nose first into the feedramp and stopping / jamming right then and there.
Dan asked what he should do, I told him to disassemble the magazine and then carefully hold the magazine budy (the “tube”) on a table or better yet a piece of wood that lets the bottom lips dangle but supports the magazine all the upwards. Then lightly tap on each front side of the magazine to close the gap. Light tap left, light tap right, and measure. Repeat until it gets to the right gap – either via measurement or testing the mag with some dummy rounds.
By the way, the back of the magazine is fixed due to the folded metal ears that form the back of the lips. You can’t adjust them much at all or they will buckle or break. I leave them alone.
This tapping doesn’t take a ton of effort so use a light hammer and light taps – this is not a “mongo smash” moment because if you crush the neck of the mag, it’s game over unless you have a mandrel to open it back up. These days I use a light body hammer to do the work.
If you go too far and need to open the lips, use malleable chain pliers also known as chandelier or lamp chain pliers to open the lips back up. External snap ring pliers can also work but are not my first choice. The chain pliers distribute the pressure along a larger area of the lips vs. the relative point pressure of the snap ring pliers’ pins.
Feed lip gaps will change with use – this is not a one time exercise and why it is a good idea to number your mags. This way you can write down the setting for each magazine or know that when you get back front the range which magazine you need to take a look at.
How did the adjustments work out for Dan? He finished a 1,000 round tactical range session with zero malfunctions. I told him to have fun because there is always something to adjust or tinker with on a 1911 and I mean that in a good way.
So, I hope this post helps you out!

In the first post, I told you about Stoner CNC for grips made from G10 composite, in the second I told you about a great option for wood – Browne Works and in this third post, we’ll cover a firm with a unique name and good grips.
The firm is called Guun Grips and they make custom G10 grips for bunch of pistol models and different styles of grips. You can find their offerings on their own website as well as tons of listings on eBay and Amazon. It’s my understanding that the grips are made in China and then sold in the US via Aurora, Colorado. So much is made in China these days that I’m not very surprised – it is interesting to note that when you search on them there are lots of satisfied 1911 and CZ.75 owners running their grip plates.
Installation was very straight forward – unscrew the pair of grip screws and put on the new panel. I did need to do some light filing on the right side to get the G10 panels to sit flat and the holes to line up accordingly. Oddly enough, the left side went right on.
Summary
The Guuun grip plates are nicely made. To be honest, I didn’t expect them to be made very well but they are – the material, machining and finishing are all very good.
So, here’s another option for you whether you want to stick with black and have a different feel or opt for their grey color.
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.

Mark Browne is the owner of Browne Works, Inc., located in Pasadena, MD, southeast of Baltimore. He is a true custom grip maker and sands and finishes them by hand with a very wide offering for pistol models including the 1911, Beretta 92, Hudson G9, Llama, SIg Sauer and, of course, the Rock Island single and double stack pistols.
For Rock Island pistols he has a wide variety of offerings for the Ultra and Tac Ultra both FS and MS models. He also has them for the A2 HC (like I needed) plus the BBR. The pricing is very reasonable also and he has a variety of materials you can choose from – click here for his website.
Installation was very straight forward – unscrew the pair of grip screws and put on the new panel. I did need to do some light filing to get the wood panels to sit flat and the holes to line up accordingly.
Now I need to insert something here that Mark did that really helped me out. The photos in this post are actually of my second set. On the rear of the grip is a tab that covers a slot. I don’t know what happened but it cracked on my original right side plate. I contacted Mark and he told me he would make a new one and add hardener and use the cool double diamond pattern and he didn’t charge me! He had no idea who I was or that I planned a blog post – I never said anything. He took care of me and that speaks a lot about him and his customer service right there.
Summary
I’m not always a wood fan but to be perfectly honest, I like these – a lot. The checkering really gives you a nice grip without biting into your hand. They are staying on the pistol!
When it comes to Browne Works for RIA A2 HC pistols – I definitely recommend them based on my experience.
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.

Because we sell customized magazines for the Rock Island A2 HC pistols – their staggered magazine pistols based on the Para design that hold 14-17 rounds depending on caliber – I am often asked if I make grip panels – the slabs that go on each side of the magazine housing. The short answer is no – I don’t make them. The next question is usually – do you know anyone who does and again, I’d answer no.
Well, if I get asked something enough eventually my curiosity perks up so I started digging. There are a couple of key things you need to know:
The Rock Island A2 HC pistols have very wide magazine wells so they use relative thin proprietary grip plates that are not compatible with regular 1911 pistols.
The bushings that are normally replaceable in a 1911 part of the A2 HC frame and can not be easily relaced. I don’t know for sure but I think they did this to keep the thickness down
They use unique screws – the screws are #10-32. Overall length is 0.205″ and the threaded shaft is about 0.145″. Advanced Tactical (the online retail business unit of Armscor) sells replacement screws and sometimes they pop up elsewhere. The key point is that they are not standard 1911 grip panel screws.
So who sells grip panels? Option 1: Stoner CNC
I found three vendors and ordered in panels for testing. I’m doing this first post on the first box I opened – no super secret selection crtieria. This first set came from Stoner CNC.
Matt Stoner is the owner of Stoner CNC located in Archbold, Ohio, and makes grip panels from G10 composite for just a ton of pistols – 1911, Kimber, Ruger, Springfield Armory, Beretta, RIA and more. I ran into one small snag – I couldn’t find any recent reviews, his Facebook page was last updated in 2019 and nobody answered emails from his website while I was searching. I kept digging and what I found out is that he also sells on eBay and on Amazon so I went ahead and ordered two sets of panels from eBay [Click here for the listing] and they arrived six days later — by the way, he also did reply to the email just before they arrived I think. My guess is that he’s like a lot of small businesses (including mine) – stretched thin trying to keep all the balls in the air – manufacturing, emails, Facebook, etc.
As of my writing this, he doesn’t have them listed on eBay or Amazon but does have the panels that you need on his website. He only offers one series of plates that he calls “Slash & Burn” under the 1911 doublestack listing on the main page. From there you can pick the color and specify what model frame the panels will go on. The RIA Short is for pistols with the factory mag well flare (the big bell bottom on the A2 HC pistols) installed and the Long model is if you have removed / don’t have the flare.
Installation is very straight forward – unscrew the pair of screws and put on the new panel. I did not need to sand anything to fit. You’ll notice the holes are a little on the large side so you can move the panels a hair if you need to. If you must trim them to fit, look very carefully at the bottom at it may be hitting the flare and just need a bit of material removed. Again , mine went right on.
Summary
They are well made, affordable and give you different color options. There is a little bit more of a positive feeling meaning I can feel the ridges and get more of a grip whereas the original RIA plates seem a tad smoother.
Bottom line, if you want something other than black then Stoner has you covered. If I had it to do over, I would have gotten another color for the second set other than black.
Would I recommend them – yes and 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.

Rock Island Armory (RIA) is a brand name that is owned by Armscor Global Defense located in Marakina, Philippines. Armscor obtained a license from the Philippine government in 1952 to begin making firearms. In 1980 it became Arms Corporation of the Philippines (ArmsCor) and in the mid-80s they bought the US brand “Rock Island Armory” and began exporting firearms to the US. They have invested in quality improvement and automation to create their wide variety of firearms offered today. They also have opened plants in the US – one in Stevensville, MT, and the other in Pahrumo, NV.
In March 2022, a Philippine TV crew visited the Armscor factory in Marakina and produced this nice video that focuses mainly on their 1911 production area:
The reason I wanted to share this with you is that RIA pistols do have a long history and Armscor is not some fly by night company. This is my opinion – I would describe RIA 1911 pistols as being designed, built and sold to shooters who want an acceptable 1911 without spending a fortune. They are not claiming to turn out semi-custom pistols – instead, good enough pistols at an affordable price point.
In marketing, when you are trying to hit a certain price point to attract the buyers you are after, you have to figure out the features, the materials, and process combination to get you there. Now reliability and accuracy are features also so this needs to be factored in – the pistols need to be good enough but not necessarily over the top – even though we wish they were.
Ok, but are the 9mm HC 17 round pistols “good”?
So let’s go back to the question – are they good? For the price, yes. You can’t compare them to far higher end pistols such as Stacatto or Bul – it’s simply not fair. It would be like comparing a daily-driver economy model Ford or GM car to a BMW. Yes, they are all cars but the engineering and attention to detail during manufacturing in the BMW are going to be very different. They are for different markets comprised on people with different disposable income levels and tastes – and have different price points.
The two pistols I am discussing to be clear are the 9mm RIA A2 HC pistols – the 51679 Tac Ultra FS HC and the 56645 Pro Ultra Match HC – by the way, FS means “Full Size” and HC means “high capacity” because they hold 17 rounds in staggered magazines.
The frames and slides are made from 4140 alloy steel via CNC and they do have QA steps. The barrel seems to be pretty decent but then the price point issue begins to creap in.
For example, to keep costs down, Armscor uses metal injection molded (MIM) parts. I know through first hand experience, the extractors are MIM and they will not have the longevity of a forged part made from tool steel such as one from Wilson Combat *but* the extractors can be replaced if you ever have a problem so it’s not like you suddenly have a boat anchor and that’s one of the beauties of 1911-style pistols – there is a huge aftermarket parts industry and tons of websites/forums out there to help you sort out what is going on not to mention 1911 gunsmiths and that Armscor has good warranty service – I’ve had to avail on it twice – one on a 6″ 10mm Big Rock and also on a 9mm Tac Ultra that had failure to extract issues … and on that one, there was something seriously wrong because just replacing the extractor didn’t work. [Click here for a post I wrote about my extractor journeys with RIA 9mms].
They also use a parkerized finish and its applied very nicely. There is a but coming – but parkerizing leaves a rough finish and means they need to wear in more compared to other brands that use a different finish and/or have careful polishing and tuning while parts are assembled.
Conclusion
This is my way of saying they are good enough. You are buying an entry level pistol that has been on the market for many years and word would get around quickly if they were utter junk. Does the gun need wear in? Yes. Might there be issues? Yes. Do they have warranty support? Yes and they do stand behind and repair their pistols.
Would I recommend these RIA Tac Ultra FS and Pro Match Ultra HC pistols to someone looking for an entry level 17 round 9mm 1911 style pistol? You may find it odd but yes I would and I’d explain the above.
I hope this helps you out.
1/6/2023 Update: I’ve had zero problems since writing this post. Both pistols have cycled thousands of times during magazine testing (meaning rounds are cycled by hand but not actually fired) and the slides are smooth as glass. I took both to the range recently and they functioned just fine with both 115 and 124gr bulk FMJ – I think the 115gr was CCI and the 124gr was S&B if I recall right.
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.

This post reflects a journey I’ve been on regarding making and selling magazines for the 9mm Rock Island Armory (RIA) FS A2 pistols. These pistols are based on Para Ordnance designs that use a staggered magazine that can accomodate 15+ rounds in a fattened 1911 grip. Think of them as 1911 pistols on steroids with a fat grip the holds more rounds they hold more rounds so sometimes RIA calls them “HC” for high capacity.
For over a year now, I’ve been making magazines for the FS A2 pistols chambered in 10mm and .40 S&W. The interesting thing is that 9mm, .38 Super, .40 S&W and 10mm all use the same frame. You’d think making the 9mm mags would be an easy jump – I did at least — maybe it was just me.
The 10mm round is bigger than 9mm – it is fatter and longer. You don’t think about that a lot until you are trying to get the ejecting case to hit the ejector – the 10mm round is a hell of a lot easier to make hit the ejector than the 9mm. Also, the relatively short 9mm round has a long way to travel before it goes into the chamber. I found myself having to kick out some assumptions I had for magazines in order to get the 9mm round to reliably work.
In general, I now understand why the 1911 community is so fast to cast suspicion on the magazines when feed and ejection problems are happening. John Browning was an absolute genius and the 1911 design shows it but it does need all of the parts to be working together correctly to deliver a reliabile pistol.
Oh yeah, the magazines can make or break reliability. Let me share with you some observations I’ve made so far about the magazine after making a few hundred of the 9mm models either modifying P18 magazines (.38/9mm) or P16 mags (10/.40).
What about feed lip length?
The feed lips are the part of the magazine that hold the top round down and at the right angle. If they are too short, the round tends to be presented at too high of an angle and if they are too long, the front gap may not be adjustable enough to support the feed angle needed.
The original 1911 was designed for .45 ACP but we are feeding a little short round from the back of the magazine towards the chamber a mile away. How can we maintain control? The short answer is have longer feed lips on the magazine. These longer lips are what get the relatively small 9mm round from the back of the magazine all the way into the chamber.
The reason I listed this section is that the length of the feed lips can vary depending on the model of pistol so if you are trying to use a magazine from another type of pistol you may find you need to trim the feed lips back. I didn’t have to change the P16 or P18 mags for the 9mm but I did need to modify the P16 Para mags to feed reliability in RIA 10mm and .40 S&W pistols.
What happens if the front feed lip gap is too wide? You tend to get a Failure to Eject (FTE) or the Slide locks open prematurely
The feed lip gap at the front of the magazine controls where the cartridge is going vertically – the angle towards the chamber. Increase the gap and the front of cartridge rises and decrease it and the angle goes down. But wait, there’s more.
Now here’s the first gotcha: The feed lip gap still controls the rise of the bullet in the front but if it goes too far, the bullet is going to interfere with extraction, pushing the extracted case upwards on the breach face of the slide and out of position to correctly engage the ejector and all of a sudden you have the old case in the slide, a new round trying to feed and you have a jam. If you go for a front feed lips gap of .305-.308″ you will be fine. Depending on your pistol once you get somewhere around .320″, you are going to cause the ejection problem I just mentioned
I’ve spent a lot of time chasing this dimension because you tend to get better feeding the more the bullet is oriented towards the chamber but with the 9mm you have to be mindful of the impacts on the the ejecting cartridge.
By the way, in addition to interfering with ejection, a feed lip gap that is too wide can allow the follower to travel too far upwards and prematurely lock the slide open with one cartridge remaining in the magazine.
I should point out that the most likely cause of a failure to eject (FTE) is a faulty magazine. The second most likely is a worn or failing extractor. It probably is not the ejector bar.
What happens if the front feed lip gap is too narrow? You tend to get a failure to feed (FTF)
If you move the feed lips to close together, the new round that needs to be fed into the chamber comes in at too flat of an angle and smashes straight into the feed ramp. On one hand the 9mm bullet is rounded abruptly but the feed ramp is quite abrupt. I tend to find that somewhere under .302″ this happens but I haven’t done a lot of testing on this dimension because I have been more focused on wanting the cartridge angled up vs. down.
Yeah, the lips have a memory
So the magazines are made of high carbon steel that is heat treated. The feed lip gap falls within a certain tolerance. If it changed either wider or narrower, the lips are going to move back towards their original positing anywhere from .002-.004″ so plan accordingly.
This is where experience matters with the mags you are working with. Once you have your dimensions figured out, you may find you need to bend further than the nominal dimension so when the sheet metal starts to relax it will stop in the range you want.
You may also find that the metal does most of its movement in some number of minutes after you do the initial tune and need to do it one more time. Some guys will wait overnight to do the final tuning. I wait at least 30 minutes.
What about left and right bends to the feed lips?
The more you bend the feed lips in one direction too much, the round will point that way and either glance the chamber wall or actually slam into the chamber and stop depending on how off you are. Try and get the cartridge to point into the center of the chamber in terms of left to right.
What about the follower?
It’s really interesting how important the follower is. On one hand it is pushing the rounds up againt the feed lips properly and on the other, there is a small “shelf” on the front left edge that pushes the slide stop lever up and locks the slide open on empty (unless you are using competition followers such as the Arredondos that purposefully do not lock the slide open).
The walls at the top of the 9mm mag really need to taper inward to properly channel the staggered round into the single exit position at the top. The follower’s sides need to be appropriately tapered and rounded as well less they drag on the walls. The original Mec-Gar followers have significant drag that you can feel when loading the mgazine so revising them made the most sense.
By the way, to make life more colorful, when you install the follower the spring tension will spread the feed lips wider by about 0.002-0.004″.
How about the spring?
The Mec-Gar springs are okay. How much spring is enough or to little really depends on how well it can keep constant upwards pressure on the follower to move the rounds up fast enough and keep them in position. With the drag on the follower reduced, the spring can do its job.
There is an exception though – if you add a magazine extension or base plate that adds capacity, the spring really ought to be longer so get a Wolff or Arredondo spring that can supply the pressure over a longer distance.
Yes, springs can and do wear our so if you feel the follower is being pushed up sufficiently or is sluggish *and* the walls do not appear bent then you probably need a new spring.
What about lubricant?
Mec-Gar mags come with some lubricant all over the insides of the mags, follower, spring, floor plate and base plate. On one hand it protects against corrosion but on the other it can attract dirt.
I would recommend that you use a good dry lubricant film. I used to use Dupont’s Teflon dry lubricant film spray but they discontinued it over environmental and health concerns about Teflon. The company is now producing a dry film using a ceramic technology that I really like and find it does a remarkable job at lubricating magazines.
If you are in a marine environment and you need the corrosion protection the use the oil of your choice – you need to worry about rust, I get it. For me, the Dupont Dry Film Lube aerosol spray does a great job. The new followers and the inside of the magazine tubes coated with this enables remarkably smooth movement of the follower.
Number your magazines
A tip you really ought to consider is to number your magazines so you can keep track of them. I like stickers because you can readily remove them if you put a baseplate on a different magazine tube but there are plenty of guys who use a permanent marker or etcher to uniquely identify each magazine.
The benefit of doing this is that when you are at the range if you find that some magazine is having problems, you can write down or take a photo of the number and know what you need to work on. Face it, if you have a bunch of mags and they all look pretty similar it can be hard to keep track of them otherwise.
We do sell the stickers if you are interested – click here.
I’m still learning
I don’t claim to know everything – let me right up front about that. I now know what people mean whey they say “The more I learn, the less I know”. In other words, as I learn more I am increasingly aware that there is a ton of stuff I don’t know.
Hopefully this gives you some insight about why one magazine will work great but then another one doesn’t. The above are things to consider.
My reason for writing this is to give you some idea of what we’ve learned and are building into each 9mm magazine that you buy from us – we aren’t just relabeling mags and selling them at a heck of a mark up.
What are are doing is ensuring the dimesions, doing the necessary modifications and testing teach magazine in one of our 9mm RIA pistols to ensure you get a reliable mag. If you have problems with a magazine from us, we will definitely make it right.
We do have a new post about how to load our v2 9mm magazines to get reliable feeding. Click here for it.
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.

Starting in 2021, I started to offer 10mm magazines for the Rock Island Armory A2 HC pistols – “A2” being a marketing opportunity to refer to the next generation 1911A1 pistol prototyping the US Army did starting in 2004 that experimented with different sights, extractors, mainsprings, etc. The “HC” stands for high capacity and reflects the RIA pistols are using a staggered magazine design to hold far more rounds than a single stack could.
At any rate, I had a number of customers ask me to produce mags for the 9mm RIA A2 HC pistols – the 51679 Tac Ultra and the 56645 Pro Ultra Match HC. Our 10mm mags had proven to be very successful and after enough requests, I decided to enter the 9mm magazine market.
One thing I learned with making AK grips is that you really need to have the weapon to make a part for it. This allows you to check fitment, reinforce potentially weak areas, etc. So, when I started with the 10mm mags, I bought a 52009 Rock Ultra HC and later a 56862 Tac Ultra Match HC. Why? Because you also find that a given firearm may differ enough that if you build and test only with it, you may not be making something others can use.
There’s an engineering problem called “stacked tolerance”. Every part has a specification that says, for example “9.0mm” and then there is a tolerance specified – for example “+/- .01”. That means the part produced can range from 8.99 to 9.01 in size. Make an assembly and all of those tolerances may combine, or “stack” in such a way that if you build a part to work for that particular unit then another assembly that happens to stack in the other direction may not be able to use that part. Testing on multiple pistols helps with a testing – at least a bit because you are reducing the odds of one pistol having a problem or working and others not.
So, by having both the 52009 and 56862 10mm pistols, I could test magazines to make sure they fed right, dropped free, etc. With the 9mm pistols, I had limited funds and just started with the 51679 – the Tac Ultra. That decision bit me hard.
The Initial Magazine Prototyping Didn’t Make Sense
When I prototype, I buy a bunch of original magazines and then start looking for what is close enough to modify and start tinkering with the feed lips, feed angles, the spring and the follower. To keep track of things, I applied numbered stickers to every magazine and kept track of the dimensions plus performance.
What I also learned with the 10mm mags is that the best dummy rounds are the machined aluminum A-Zoom Snap-Caps. Dummy rounds that are made from a case and a bullet will see the bullet pushed back into the case and/or get deformed after some fairly low number of cycles. The machined aluminum A-Zoom Snap-Caps are dimensionally accurate and can cycle hundreds of times before needing to be replaced. By the way, don’t do this type of work with live rounds – it’s an accident waiting to happen.
Back to the 9mm world, I was working on the mags and things just didn’t make sense. A magazine would work and then it wouldn’t. One set of dimensions would work and then they wouldn’t. Something just wasn’t adding up. The pistol would fail to eject randomly, I’d then have the old round and the new round in the slide at the same time and of course it jammed.
It had to be the mags right? I blew through a bunch of mags and time before it dawned on me that the pistol itself must have issues. I hadn’t questioned it before because the pistol was brand new out of the box. Sure, I had cleaned and lubed it first before cycling hundreds of snap caps through it. The problem was that I assumed it was good to go and the initial testing seemed to show a reliable pistol … but I only tested a few mags worth of snap caps – maybe 34-52 cycles max.
Testing The First Pistol
I loaded a magazine up, racked the slide and loaded a snap cap. I then pulled the slide back slowly and the extractor lost control of the extracted round as I pulled the slide to the rear. That wasn’t supposed to happen. If I went slow, it would either fail to extract completely or lose control of the round.
I’m not a 1911 gunsmithing guru but I had to learn some stuff really fast. I knew if I sent the pistol back to Rock Island/Armscor, it would be at least a month before I would get it back. So I read posts and watched videos that explained the pistol had an extractor problem and how to correct it. I bought a few different brands of 9mm extractors, the Brownells extractor tool, the Jack Weigand extractor gauge and tensioning tool.
Boy, I could not get that thing to work even after trying a few different brand extractors and a Wilson. At this point I was pretty ticked off. My last best guess was that the extractor looked like it was clocked slightly. When I inserted the Weigand 9mm gauge, I could feel initial tension as I inserted it and then it would drop off rapidly as I inserted the gauge the rest of the way (it centers over the firing pin hole). Rather than do a new firing pin stop plate, I decided to stop chasing best guesses mainly because I was blowing time I did not have to spend. The pistol was under warranty so feeling both stupid and defeated, I finally got an RMA to send the pistol back.
No, I’m Not Incredibly Patient
In the meantime, I bought a 56645 Pro Ultra Match HC and it has worked great – no problems at all. I was able to work out the details on the mags. Now, I am not patient so I actually ordered a second 51679 Tac Ultra that I looked at, cycled a few rounds through but really didn’t use a great deal – my primary go-to test platform was the 56862 … until I decided to take some photos about the RIA 9mm A2 HC pistols and looked at the 51679’s extractor.
“You’ve got to be kidding me” – I thought to myself. Inserting a choice F bomb of course. The extractor in the brand new 51679 that probably has less than 100 hand cycled Zoom snap caps through it was almost completely broken off other than a little tiny nub on one end. WTF?!?!
Okay, two 51679s bought from different vendors off Gunbroker about a month apart both having extraction problems …. wow. I’ll be honest – I’m disappointed. RIA 1911s are econobox models but they usually work – so, no, I’m not remotely happy not to mention jumping through hoops waiting for ever for their customer service to respond. I did learn a bunch though and will share with you what I did and what you can do if you want to.
Metal Injection Molding For Extractors Isn’t The Best Choice
The problem is that to keep costs down, Armscor, who owns the Rock Island brand, make the ejector using Metal Injection Molding (MIM). If you search on the web, you will see a ton of guys arguing against the use of MIM in high stress parts. As I just learned with extractors, it’s not the strongest manufacturing approach – making them from forged high-quality steel is a far better idea.
Okay, if you get a new RIA 9mm pistol, check the extractor out of the box. Clean and lube it, go to the range and keep your eye on the extractor. If it breaks you have two options – send it back to Rock Island/Armscor for a RMA repair or do it yourself. Heck, you could even just replace the extractor yourself before you have a problem if you want to.
I Decided To Replace the Extractor Myself
I learned a ton on that first pistol plus I had all of the tools and spare Wilson Combat extractors. I just needed to trust in my abilities a bit more and try it again. If there’s one thing I know about myself, it’s that I am persistent and don’t give up easy. With this in mind, I dove back in again with far better results.
Fully Machined from S7 shockproof tool steel with a tensile strength of 275,000 PSI
Optimized hook design for maximum strength and case rim contact
Hook location tolerances held to +/- .001″
Radiused corners for extended life and smooth feeding
Enhanced design holds tension longer over factory part many times over
Heat treated to optimum hardness and cryogenically treated
Guaranteed for life against breakage or we will replace at no cost to you
Note: I went with a series 80 extractor because they were in stock even though the RIA pistols are based on a series 70 design. You can use a series 80 extractor in a series 70 pistol but not vice versa. You can get them from Brownells, Wilson directly and other places.
Recommended Tools
You don’t need specialized tools but if you can afford them, I would highly recommend the following:
Weigand’s extractor tension gauge set – let’s you precisely dial in extractor tension. Note, I did add a brass s-hook so I can grab it with a trigger pull gauge more easily.
Lyman – Mechanical Trigger Pull Gauge – even though I have some digital trigger pull gauges, I lacked a mechanical unit and there are times where it is handy to see an analog scale changing vs. flashing numbers you can’t read so I bought it regardless. Yes, if you have a trigger pull gauge already, you can use it.
Make sure your pistol is unloaded – that the chamber is empty and a loaded magazine is not inserted. In short, work safe. Also, do not use live ammo for testing – use snap caps.
Let me give you an overview and then a couple of videos to watch:
Remove the slide
Remove the firing pin stop plate by pushing down with the straight short end of the extractor tool and then slide the plate off. Be CAREFUL that the firing pin and/or spring don’t come flying out as you remove the plate.
Push the extractor backwards by pushing the head of extractor backwards down the hole out the rear of the slide
Insert the new extractor and line it up so the stop plate can be re-inserted. It needs to line up with the top and bottom of the stop plate groove and it needs to be straight up and down parallel to the sides. You don’t need to install the firing pin and spring until you are done.
Insert the Weigand gauge and pull it out using the trigger pull gauge to find out how many ounces it takes.
Use the Weigand tensioning tool to increase or decrease the tension. I dialed mine in to 28 ounces (1.75 pounds).
You can try testing feeding and extracting dummy rounds to see how it performs. The extractor should maintain control until the extracted dummy round hits the ejector.
Once it is dialed in, you can then re-install the firing pin return spring, lube the firing pin and reinstall it also.
There’s a trick to the plate – wiggle it in and push down the firing pin enough to get the plate to sit on the “shelf” at the rear. You can then maintain pressure on the plate and use the other hand to use the extractor tool to push the firing pin down far enough and hold it there while you push the plate back into place.
More Details
Wilson has a video on how to change to their extractor and a bit about setting the tension:
The following is a video of Jack Weigand explaining how to use his extractor gauges and tensioning tool:
Adjusting The Extractor Landing Pad
The most detailed post and guidance in general about extractors that I read is here – and if you read down, you will get to sections/replies about 9mm extractors. One thing you will notice discussed is reprofiling the “fitting pad” to better fit the radius of the extractor hole. I stoned and polished the fitting pad to be more rounded but that was it. I put more emphasis on getting a weight in the 25-28oz range and did do that after may 3-4 tries.
Was The Match Pistol Higher End?
I wondered if maybe more care was put into the match pistol. There are some nice perks in terms of features but the trigger feels about the same between the two pistols. I’ll write up something more detailed down the road – for now let me just say they pistols are not night and day different in terms of how they feel with cycling the slide or pulling the trigger.
In terms of pricing, there’s not a huge difference on Gunbroker. The first 51679 was bought on 3/5/22 for $819.99, the Match pistol was $899.00 on 3/25/22 and the second 51679 was bought on 4/3/22 for $899.00 also. In writing this, it’s surprising that the Match wasn’t $100-200 more on the street but it wasn’t. If you look at the manufacturer’s suggested retail price (MSRP) – Armscor did set the 51679 at $899 and the Match 56645 at $1099. In other words, Armscor was hoping the Match would command a premium.
You can find the 51679 pistols right now with a bit of hunting. The 56645 match pistol is challenging to find as it seems to be a bit more rare now but it is out there too. I’d tell you to get the 56645 Pro Ultra Match HC if you can find it. As you can imagine, I’m not too thrilled with my 51679 experience right now and there is little to no price difference *if* you can find one.
Conclusion
I’m not sure what to tell you about what happened – I only have data from two 51679 pistols and one 56645 pistol. It could just be really bad luck – neither of my current 10mm pistols have given me any trouble and the 56645 Pro Ultra Match has been fine so far as well although I have only cycled maybe 500-600 snap caps through it so far.
The first 51679 had something going on that I can’t explain and am waiting on Armscor to fix it under warranty. It certainly was not a broken extractor. For the second one to have a snapped extractor claw with so very few rounds – I guess that highlights the limitation of MIM and that forged extractors are better – there’s a reason why Wilson’s Bullet Proof extractors have such a good reputation.
6/22/22 Update: RIA did a warranty repair after about 4-5 weeks. All they told me was that they confirmed the extraction problem, fixed it and the pistol was fully operational now. So, I still don’t know exactly what happened but at least Armscor/RIA stood behind it and made things right.
We’ll see what Armscor comes back with regarding the first pistol and I’ll report it here. I guess the big thing I want folks to know is that changing an extractor is not an arcane black magic endeavor. There are tons and tons of videos and posts that you can read. At some point you just need to wade in, give it a go and learn.
My other lesson learned is that don’t replace a busted Armscor extractor (MIM) with the same thing. Upgrade. I decided to go with Wilson Combat due to all the good reviews I read and would recommend that.
I still have a lot to learn about 1911s and don’t claim to know much. I’m really focused just on the mags but I hope this helps out anyone who reads it.
A Stunningly Good 1911 Reference Book Recommendation
6/29/23 Update: The match 9mm MIM extractor is still doing just fine and I have no idea how many thousands of times it has been cycled. The Wilson is doing great on the other pistol also.
12/17/22 Update: I’m somewhat surprised – the original MIM extractor in the Match 9mm is still doing just fine thousands of rounds later. So is the Wilson but I am not surprised about the Wilson holding up.
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.
