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:
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.
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.
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.

I posted about 9mm magazines for the Rock Island Armory (RIA) FS A2 pistols and a friend on FB, pointed out they weren’t 2011s. The difference being the 2011 has a modular grip assembly and the RIA pistols are just over-sized 1911s. It dawned on me that I really didn’t know the difference and needed to do some reading.
How “2011” originated
It turns out that Chris was right – there is a difference – a substantial difference.
From what I have read the original 2011 concept was essentially a modular 1911 receiver that could have the mag well / grip sub-frame swapped out to allow for more versatility. The 2011 design and patent was by Virgil Tripp and Sandy Strayer who together formed STI and then went separate ways and shared the patent,.
The design is really cool and the best way to help you learn more is to provide you a link to the original patent application that has written descriptions and drawing — click here to see the orginial patent.
Back to the Rock Islands
The RIA pistols are oversized 1911 pistols. The grip and mag well area are integral parts of the frame and can’t be separated plus they use thin grip panels.
In Closing
So now I know a bit more about the differences between the 2011 and 1911 designs. The RIA pistols are oversized-1911 designs and not true to the original 2011 design concept.
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.

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.
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
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.
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).
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 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.
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.

Firearms box magazines all work the same – a spring is pushing against a follower that is then pushing the ammunition on the direction needed. The follower is often pushing against at least one wall of the box magazine and dragging. This can be especially bad with steel and aluminum magazines making loading the magazines more tedious and even cause problems with feeding. It begs the question – how can I lubricate the inside of the magazine?
The knee jerk reaction is to put oil in the magazine to lubricate things. I’d recommend against this course of action because the oil will trap dirt and eventually can start causing sticking and jamming.
I’d recommend that you use a dry film lubricant aerosol instead. These sprays on and then the liquid evaporates off and what is left in place are thousands of particles that are slippery. I do not recommend any of the dry films that include a wax – like chain lubes. The wax may trap dirt as well over time.
Don’t spray anything in, or on, a plastic magazine without first checking with the manufacturer. Some plastic magazines are self-lubricating and don’t need any additional lubrication. Also, when spraying any solvent (which is basically what the dry film particles are floating in) on plastic, you risk the plastic getting gummy due to a chemical reaction – this depends on what plastic they useed. My recommendation is really for steel and aluminum magazines.
A Quick Side Note About Teflon
Up until a few years ago, I used to like Teflon, which is what Dupont, the owners of the trademark call it. Teflon was discovered by Chemours, which was a spin off from Dupont, in 1938. If you see someone selling “PTFE” – that is the generic name for Teflon. By saying their product contains “PTFE” then they don’t have to pay royalties to Dupont or risk having Dupont sue them.
So, Teflon and PTFE were selling great and then people started worrying about the safety of people eating Teflon, Teflon in the environment and so on. I’m not hear to weigh in on this but whether it was concerns over marketing, lawsuits or just the pandemic, the Dupont Teflon Aerosol Spray went on hiatus for the longest time.
In late 2021, it re-appeared but with a different formulation. The new spray uses a ceramic now and not Teflon. I corresponded with Hank Krause the president and CEO of Finish Line Technologies – the group that actually markets the spray. I was concerned about the change in formulation because the Dupont spray had been excellent before. Want a quick way to test this? First, spray some competing dry films on a black plastic surface and see how some of them actually leave very little residue. Also look at how evenly the distribution is. Not all are the same.
Nano-Ceramic Boron
At any rate, Hank told me that they have moved away from Teflon to Nano-ceramic boron nitride particles and I told him my concern that I didn’t know whether to change to a new dry film technology I knew nothing about. Hank told me the new formulation used thier same propretary technology for binding the particles to the surface and the following are benefits of the new ceramic technology over Teflon (I will copy and paste his list verbatim):
Helps extend life of the lubricant, thus delivering longer relubrication intervals
Provides enhanced lubricity
Provides better extreme pressure capabilities
Increases the high temperature operating range of the lubricant
Provides better resistance against chemicals
Helps repel water and moisture more effectively
So, based on Hank’s assurances, I ordered in some cans of the spray and started testing them. The residue looked very similar to the Teflon test above – the ceramic dry film residue is also white.
In terms of lubricity, it does the job just as well and maybe even better than the Teflon. While this may seem subjective, the lubrication seems very good with one solid spray of the ceramic both in the tube of the magazine and on the follower. Any over spray wipes right off with a rag.
With the ceramic spray, feeding rounds by hand into the magazines and unloading all feel very smooth. Bear in mind that this comment is after hundreds of loaind and unloading cycles by your’s truly.
Our new second generation followers for our RIA 9mm magazines are converted from OEM followers with the final step being fine sanding paper. It’s my speculation that the ceramic particles are getting into the tiny grooves of the follower and providing excellent lubrication.
At any rate, I am very happy with the new Dupont Ceramic Dry Film aerosol for use inside firearm magazines and wanted to pass along the word. Going forward, we are using the Dupont product in all of our steel magazines that do not already have an anti-friction coating (AFC).
By the way, I cleaned out a bunch of IMI Galil magazines that I bought and you could tell there was a bunch of friction going on in the mags between the parkerized tubes and followers – the parts hadn’t worn in yet by any means. With the mags disassembled, I sprayed in a heavy coat of the Dupont Ceramic Dry Film in the tubes and sprayed both the followers and springs, let them dry and re-assembled the mags — wow! What an amazing improvement. Click here for the Amazon Listing.
I hope this helps you out.

Well folks, at one point I had three 1911-style 10mm pistols. A Magnum Research Desert Eagle (model DE1911G10), a Rock Island Armory (RIA) Rock Ultra FS HC (model 52009) and a Springfield Armory TRP Operator (model PC9610L18). While I like the 10mm cartridge, I didn’t really need three pistols so I decided to take them to the range to decide what I would keep and what I would sell.
The Ammo
I took with me about 200 rounds of Ammo Inc’s 180gr TMC load that I had purchased from Palmetto State Armory during one of their daily deals. TMC stands for “total metal case” – meaning the lead is fully encapsulated by the copper jacket. With full metal jacket (FMC) ammo, the base often has the lead core exposed. Ammo Inc is interesting in that they decided to go the public company route and we’ll have to wait and see how they fare when the panic buying dies down.
I also took about 200 rounds of Sellier & Bellot (S&B) 180gr FMJ ammo as well. It’s been my “go to ” 100 range ammo for years. If you don’t know S&B, they are an excellent ammunition producer located in the Czech Republic dating back to 1825.
For the past six months, finding ammo has been a bear but suppliers are starting to build up inventory. Judging by my inbox, more and more emails are being sent saying “we have ammo in stock” and even a few sales. These tend to come shortly before prices start to drop based on past panic buying ammo shortages [click here for my blog post on the economics of ammo during a panic].
The Range
It was a beautiful March day when I arrived at the Berrien County Sportsman’s Club to use the pistol plate range. The plates are about 30-35′ feet back from the firing line and I had it all to myself.
BCSC is my favorite range hands down and I have been a member there for many years. Definitely a cool place for a variety of sportsman and family activities.
First, the 6″ TRP Operator
As I have written in the past, the TRP Operator was not reliable out of the box and this was a do or die outing for the pistol in terms of whether I would keep or sell it. The TRP Operator is basically a 6″ 1911 and the marketing would lead you to expect that it would have been stunning out of the box but it wasn’t to be perfectly blunt.
Thankfully, after work both myself and Springfield Armory’s repair groups did, it finally handled the way it should have when I first got it. This time around, functioning was reliable and the recoil was handled nicely by the heavy pistol with it’s 6″ bull barrel.
I was able to fire round after round at the plates at 30-35 feet and hit them. I really wasn’t shooting for benchrest accuracy – just shooting at plates to decide what to do.
In summary for the TRP, it ran just fine but it did nothing to wow me.
Next – The Magnum Research Desert Eagle (model DE1911G10) by Bul Armory
Okay, next up on the testing list for the first time was my new Desert Eagle 10mm that is actually made by Bul Armory of Israel. Out of the box it had the best trigger of any 1911 I have owned and the action was very smooth.
Let me sum it up and say – I really, really like this pistol. It functioned flawlessly and felt great. With the TRP, I was not impressed by the time it finally worked right. The Bul’s performance was nothing short of fantastic.
Last But Not Least: The Rock Island Armory (RIA) Rock Ultra FS HC (model 52009)
This was the first trip for the RIA Rock Ultra FS HC – let’s just call it the 52009. I wrote a blog post about my first takes and things were looking good so far. At any rate, I knew with the RIA pistols that you needed to clean and lube them plus I slightly beveled the chamber edges and polished the ramp.
I was really curious to see how it would function not only in general but also with the new magazines I was making for them. I also wanted a higher capacity 10mm 1911 if possible so there was a lot riding on the trip.
To sum up the 52009 – it was starting to wear in and felt surprisingly good. I sure missed having the front serrations on the slide because by the end my hands were starting to ache and my ability to squeeze hard enough to hold the slide and rack it was dwindling.
Once I identified the good mags and problem mags and focused my efforts, it ran great. I was quite pleased with it and I can tell you now that I have cycled it thousands of times fitting magazines, it is quite smooth. The 52009 and RIA 1911/2011 pistols in general are really good examples of parts need to wear in, or get to know each other, to get rid of tiny burrs/imperfections left over from manufacturing.
Would I buy it again? Yes. Was it my first choice? No, actually it wasn’t. I really wanted a high cap 5″ pistol styled after one of their Tac or Tac Ultra pistols that has the forward serrations and a Picatinny rail on the bottom of the frame. The reason being is that they are lighter and more compact than the 6″ Big Rock that I had years ago. Their 56862 model has a 5.5″ threaded barrel (hence the extra half inch) that I would have preferred but with the panic buying, it is impossible to find. Who knows – I may find one some day.
In the mean time, my only wish was that the 52009 hand front serrations – other than that it is a solid pistol.
Final Decision
As you can probably guess, the TRP Operator was voted off the island and my friend, and FFL, Scott Igert sold it for me. I felt pretty good about the decision too.
What’s interesting is that if you go to the Springfield Armory website today – the 10mm TRP Operator is gone. It could be that the demand just wasn’t there. I talked to a fellow at Dawson Precision awhile back about Stacattos (STI changed their name a few months back) and if they had any 10mm pistols because they used to have a number of models including the “Perfect 10.”) At any rate, he told me the demand just isn’t there – everyone is going for the 9mms these days. That might be the case for Springfield though I notice they are offering their Ronin model in 10mm.
That’s it for now. I hope you found this post useful.

Hi folks – this is my second Rock Island Armory (RIA) 15 round 10mm 1911 high cap-style pistol that I have owned. My first one was a 6″ Rock Ultra that I sold years ago because I didn’t really need it. Lately I have gotten back into 10mms for situations where I need to pack a punch such as back country hiking in black bear country.
At this point, I have two 10mm pistols. My 1911-style Desert Eagle and now this 2011-style RIA 52009 Rock Ultra FS HC. FS meaning Full Size – it’s based on a series 70 5″ 1911 in terms of the action. The HC means high-capacity because it uses a staggered 15 round magazine that means the pistol can hold 16 rounds when topped off with one in the chamber.
In my opinion, Rock Island pistols are work horses. They may have a very plain parkerized finish and be a tad rough but they were made for use – not just sitting in someone’s safe. In terms of the rough action, they do wear in and give you a very good pistol.
In the case of this 52009, the pistol was well assembled and just felt a little rough. Folks, this is just fine in my honest opinion. What happens is that the parts are made and assembled. There isn’t a ton of hand polishing and tuning going on like when you buy a high end pistol but the fundamentals are there.
The way you address this is to clean the brand new pistol, lube it really well and then use it. What happens is that the parts get to know each other – surfaces start to wear together and smooth out. Sure, you could take it apart and do it by hand but just using it can make a world of difference so don’t judge it right out of the box. I use Superlube grease on the parts that slide and their oil/liquid on the parts that rotate.
The only thing RIA honestly did wrong was forget to pack one of the unique 15 round magazines with the pistol. These mags are normally available but with all of the panic buying and COVID screwing up supply chains, they are next to impossible to find. Armscor USA would not even reply to my emails and it wasn’t until Reed Sporting Goods, the Gunbroker seller I dealt with, got a new Armscor/RIA sales rep that I was then able to get a single mag. By the way, Reed is great to deal with if you see them on GB.
The missing mag irked me but I realized there was a business opportunity and made a bunch more for myself and to sell [click here for that story] and click here if you want to buy one. By the way, after hand cycling my slide hundreds and hundreds of times while testing those mags, it is nice and smooth now.
It came coated in oil to protect the steel more than anything but you always want to take a new pistol apart, clean it and then lube it. The 52009 has been to the range a couple of times now and I definitely like it.
I definitely like the pistol and we are still getting to know each other. I did polish the ramp and chamber. In the next blog post, I’ll tell you about my range trip with my three 1911/2011 10mm pistols and the one that got sold after – which is why I said I now have two at the start of the post.
August 24, 2024 Update: Still have the pistol and it runs just fine. I don’t think people know how good these pistols are. I can’t guess how many rounds I’ve put through mine – well over 1,000.
I hope this helps you out.
