I’ve had a number of 1911-style pistols over the years from Dan Wesson, Rock Island, and Taurus. Now, I have a 10mm 1911 TRP Operator with a 6″ barrel. The one thing I learned years ago is that you need quality magazines to help with reliable feeding. I word it this way because there are many different design elements that need to be executed correctly and the pistol to be adequately cleaned and lubricated — it’s not just the magazines that cause the 1911s to either work or have problems. With that said though, they are an important piece of the puzzle and going cheap isn’t something I would recommend.
Over the years, I’ve had two 10mm 1911 magazines recommended to me that both work great with my TRP Operator. One is the Wilson Combat 47NX and the other are the Tripp Research CobraMags and I’ve used both their 9- and 10-round models. Both brands of mags work great and I have no reservation recommending either.
I’ve shot a variety of Underwood HP and hard cast rounds as well as S&B 180gr FMJ out of my mags without any problem and have no had to do any tuning to the feedlips, etc. They just work.
So what do I recommend?
Honestly, I’ve had very good luck with all of them. I prefer the 9-round magazines from both Wilson Combat and Tripp Research. The 10-round magazines stick out quite a bit and I save them for the range, hunting or some other situation where length doesn’t matter.
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.

After I finished polishing the chamber of my new 10mm TRP Operator Longslide, I also replaced the VZ Grips. Maybe it’s my carpal tunnel but I really prefer rubber grips on my single-stack 1911-style pistols. Fortunately, the Hogue 45000 wrap around rubber grips fits great.
Replacing the Grip Panels
I did some digging and the Hogue 45000 rubber grips are a drop in replacement rubber grip set for Colt-Government size frames including Springfield Armory pistols. Sure enough taking them out the package they lined up just fine.
To remove each panel, you will need a Torx 15 (T15) bit and I would recommend a container to hold the screws. I like using a magnetic tray to avoid them bouncing around.
On the topic of grip screws, you have some options to avoid lost screws. First is to use a medium-strength threadlocker and another is to put an O-ring under the head of the screw. Some guys use #61 plumbing O-rings and others use 1.5x3mm Buna-N O-rings. I’d recommend one of the two vs. nothing.
Conclusion
The pistol passes testing with flying colors – it now cycles fine, the slide and everything operate very smoothing during manual testing and the grip makes a huge difference for me in terms of comfort. Now, I just need to get some range time 🙂

Sources For the 10mm TRP Operator and Ammo
Here are some reputable vendors you can order either the 5″ or 6″ TRP Operator plus ammo:
After the very disappointing performance of my new 6″ 10mm TRP Operator at the range, I knew I had two options. First, I could send the pistol back to Springfield Armory for repair or two, I could try just a bit of light polishing first. I had good reason to want to try the second option first.
In looking at the brass coming out of the TRP during test firing, it was getting very scratched and in some cases actually nicked/gouged as it went up the feed ramp and pivoted to then be pushed into the chamber. The rounds that stopped dead and would not feed had to be tapped out with a cleaning rod. They all had a slight nick/gouge in the case where the edge of the barrel literally bit into the brass effectively locking the round in question in place.
I sure wasn’t happy at the range but at least I had a plan of attack. When I had time a few days later, I waded in to try fix the problem.
Before you ever work on a firearm, make sure it is not loaded. Be sure to check the chamber and do not have a loaded magazine in it either.
Disassembly
The 6″ TRP is a slightly odd beast. It does not have a traditional guide rod. You disassemble it just like any other 1911 by pushing the slide forward to the point the slide stop aligns with the disassembly notch and pushing the slide stop out. I don’t know of any tricks to unload the unique recoil spring system the 6″ Longslide TRP has.
As you move the slide forward off the receiver, be prepared for the spring to want to jump out so be sure to have a hold of it before you get the slide half way off exposing it forward of the browning link.
The spring system is annoying during disassembly and re-assembly but I am getting used to it. I checked with Wilson and Dawson plus did some googling around and nobody has anything to replace it so I’ll just deal with it.
The Barrel
Okay, I took the barrel and looked at the point where the steel transitions from the feed ramp to the chamber. It wasn’t polished and it was practically a knife edge. No wonder the rounds where getting torn up or even caught on that sharp edge.
To address this, I got out my Dremel, rubber abbrasive bits, some felt bobs and also a bit of 800 grit polishing compound.
One thing to remember up front – you do not need to take off a ton of material so use a fine grit abrasive and a relatively low speed. You want to work a bit and test until you get it right where you want it.
Greased the parts that slide
When we were at the range, I noticed the action was sluggish at times. This is to be expected during the break-in/wear-in period of any firearm. What I do to help the parts get to know each other is to use an acid brush to apply a light film of SuperLube grease to the parts that slide. Not a ton – just a film. For the TRP, I put it on the slide rails, the bottom of the slide. the exterior of the bull barrel and in the slide where the barrel passes. Wow – what a difference. The slide feels smooth as glass now. I also again put a drop of SuperLube oil on the trigger, hammer, browning link, etc.
Re-assembly
Putting it back together takes some practice – re-install the barrel and try to hold the recoil assembly in place as you slide on the receiver. For me, it’s easier if I do it with the slide inverted (bottom up), hold the slide and spring with the left hand while guiding the receiver into place with my right. One the receiver is on about half-way, the spring is adequately captured. Now, this also means that when you go to re-install the slide lock, you are fighting the tension of the spring. I support the pistol on a table during this step and am getting better at it. If someone has found a magic trick, please email me 🙂
Test Feeding
The proof is in the pudding right? I had to test in my shop vs. the range so that meant I needed to be very careful about where the pistol was pointed. Do what you are comfortable with and be safe.
I loaded up three magazines with three rounds of each to start. All hand cycled just fine. Prior to the above tuning, I could not do that. I then loaded up full mags of each and repeated the tests – everything hand cycled just fine.
Conclusion
I hope to get to the range at some point this week to verify the results. I fully expect it is good to go now. Also, let me again use this opportunity to point out this is why you always need to test your combinations of pistols, magazines and ammo. The TRP Operator is an excellent pistol but I knew not to rely on it out of the box. There are just way too many variables to take that gamble.

Sources For the 10mm TRP Operator and Ammo
Here are some reputable vendors you can order either the 5″ or 6″ TRP Operator plus ammo:
This post is continuing on the story of my newly purchased Springfield Armory TRP Operator 10mm Longslide. I’m going to touch on three topics – the initial mags, ammo and my first trip to the range.
The Magazines
The pistol comes with two 8-round magazines that flush fit with the bottom of the grip. My experience with factory mags is mixed so I bought four Wilson Combat 47NX magazines to use as well plus they hold 9 rounds and have a bumper on the bottom.
I tried a factory magazine with one of the S&B 180gr FMJ rounds I bought and it immediately jammed on the first test, and the second and the third. Okay, I really wasn’t surprised given past poor experiences and tried one of the Wilsons. The round went right in. I thought that fixed the problem and we’ll come back to that later when we discuss the range.
The Ammunition
With my Rock Ultra and Bruin, S&B 180 grain FMJ proved to be a very decent range ammo so I bought a few hundred rounds of it to break in the TRP.
In the 10mm community, Underwood has a great reputation and I had also used it with both of my previous 10mms. This time though, I bought 5 boxes of 220gr hard cast for bears and 4 boxes of 200gr XTP to try out.
The hardcast comes in at 220 grains and the bullet is a “Hi-Tek Coated Hard Cast Flat Nose” and the Brinell Hardness Number (BHN) is 41. That puts it somewhere between copper at 35 BHN and Hardened 6060 Aluminum at 75BHN. Pure lead comes is at 5 BHN. In short, you’d expect it to penetrate without mushrooming easily – which is what I would want for a bear’s skull for example. The round pushing the bullet 1200 FPS and 703 ft/lbs at the muzzle makes sure it gets delivered hard.
The 200 grain XTP was what the vendor had in stock at the time. I like XTP bullets in general as they perform well in terms of mushrooming so this is not something I would use on a bear but two legged predators maybe. Underwood reports that the muzzle velocity is 1,250 FPS with 694 ft/lbs.
The S&B 180 grain FMJ is for the range. In the past I found it affordable, reliable and accurate enough for practice. S&B USA reports that it’s exiting the muzzle at 1,165 FPS with 544 ft/lbs of energy.
A Quick Cleaning and Lubrication
I ran a couple of 10mm RamRodz down the bore to clean out the accumulated gunk from the factory and travel. I then applied Superlube to the frame rails and other lubrication points on the pistol.
The First Range Experience
The weather was perfect for going to the range and both Niko and I commented that as we lugged firearms, ammo, targets and what have you down the shooting lane we planned to use.
First up for testing was the TRP operator. We loaded the Wilson Combat mags up with the S&B ammo, loaded the first round, fired and it jammed. Well crud. It was jamming hard too – the bullet was hitting the top of the chamber during feeding but not rotating enough to then go the rest of the way forward. After a few of these we noticed that the transition point between the feed ramp and the chamber was actually indenting the brass enough to cause a notch and stop the round hard. So much for the S&B at that point.
We then switched to the hard cast and the TRP relatively liked that. It fired a lot more with fewer jams. What we noticed was that the angle on the hard cast bullet seemed to be such that it helped the round to properly chamber most of the time. So, we shot about 20 rounds in total and decided to move on to the 200gr HP.
Wow – the Underwood 200gr XTP load was jam city. I could not get them to feed at all. So, disappointed, we stopped shooting the TRP and put it away. In looking at the cases, I was betting that I needed to slightly bevel the transition point and polish both the ramp and chamber. Doing that will be the topic of our next post — and yes, it did make a world of difference.

Sources For the 10mm TRP Operator and Ammo
Here are some reputable vendors you can order either the 5″ or 6″ TRP Operator plus ammo:
A few months ago while hiking in the Smokies, we got up close and personal with some black bears including a sow with cubs. Neither encounter was planned of course. We were about half to three fourths of the way back to the parking area from Laurel Falls and it was near dusk when my daughter rounded the bend of the trail and shouted out “bear”. Not what I was expecting.
I went to the front of the line and saw a juvenile just as startled as we were about 50 feet ahead. I had drawn my 9mm SIG P365 that was loaded with Critical Duty +P ammo but also knew it was woefully under-powered and was literally praying that I would not need it even though Critical Duty is supposed to have some degree of barrier penetration. I was telling the bear firmly to go away and we made a bunch of noise. The bear really had a “oh crap it’s humans look on its face”, immediately looked for an exit in the brush and left the trail. No drama at all. I think the foliage and all the turns in the trail had muffled the noise of our six person group. As we left the area I kept checking behind us just to be sure it wasn’t following us.
You can’t make this stuff up – we had hiked Laurel Falls during the day so many times and never seen bears. However, 10 minutes later we saw two cubs in a tree maybe 25 yards off the trail and down a slope and the sow was at the bottom looking at us. What worried me was that she stood up and walked parallel making sure we were not a threat. We stayed as far away as we could on the trail and I was talking to the bear as we all walked down the trail. She made sure we were leaving and watched until she sat down and started eating berries. When she did that, I knew we were okay and we walked the remaining 15-or-so minutes to the parking lot.
Okay, I did a lot wrong in hindsight. We did not think we would encounter bears on this trail that we’d walked many times before without seeing anything and then we had two encounters. Walking at dusk likely played a role. I didn’t have my bear spray with me and a 9mm would not be my first choice of a backup pistol. We were lucky in that the bears were genuinely not interested in us at all. These things went through my head as we went back to the hotel that night and during our drive home.
Thinking About What To Carry Next Time
When we go back, we will be carrying bear spray – no ifs, ands or buts. Bear spray works 90+% of the time to deter a bear and there is research to support it. Also, a bear can cover a ton of ground astonishingly fast. I read 44 feet in 2-3 seconds and that also means you aren’t going to have a ton of time plus you may have a moving target to try and hit. A fog of pepper spray deployed in front of the bear is a good first line of defense … but what if the next bear is part of the 10% that doesn’t stop?
The more I thought about it, the more I wish I had not sold my 10mm Dan Wesson Bruin. At the time, I needed the money more than I did the pistol even though it was amazing. I’d read plenty about guys carrying 10s in bear country with heavy hard cast loads for penetration of a bear’s skull — by the way, you shoot for the head because all the layers of fat, muscle and bone in a big bear are liable to work against you.
After a lot of thinking, I decided to get another 10mm along with some stout loads with hard cast bullets before our next trip. My good friend Scott Igert of Michigan Gun Exchange has long told me how impressed he is with the Springfield Armory TRP Operator pistols. As a retired police officer with tons of firearms experience, I put a lot of faith in his opinion. I told him my story and he recommended the 10mm TRP Operator.
Enter The TRP Operator
Scott and I both like 1911 style pistols and how they feel. My one quirk is that I like long slides so I told him to order me the 6″ version. I like how the longer pistols feel and also how they absorb some of the recoil. The downside is that finding holsters usually requires custom work and I knew that up front.
After waiting about a week, Scott messaged me that the PC9610L18 TRP Operator Longslide had arrived. Needless to say, I went right over to get it.
The TRP operators are just wicked. The slide and frame are forged steel and sport a massive forged stainless steel match bull barrel with a 1:16 twist. It’s a “fully supported” barrel in that the feed rap is part of the barrel and no part of the cartridge case is left dangling once chambered. It also has a small notch at the rear to let you see if there is a round in the chamber.
The sights are adjustable and use tritium for illumination. They work very well.
The pistol weighs 45 oz (2.81 pounds) empty with a nice balance. It’s 9.6″ long overall and about 5.5″ tall. The grip angle really works for me and feels way better to me than a Glock’s angle. The one thing I didn’t care for were the grip panels. SA puts these “VZ Alien G10” grips on the pistols and they are very nicely done. It just so happens that I really prefer rubber Hogue grips on my 1911s so that is a personal preference thing.
All in all, it was a functional piece of art. It did feel gritty and dry but I tend to expect that with most firearms these days.
Summary
This gives you and overview of the pistol. In the next post I will talk about the ammo and magazines.

As some of you may know from a previous post I did, my Big Rock would not feed Underwood 10mm ammo. Neither Armscor/Rock Island nor Underwood helped resolve my issue though Armscor did take the pistol back and tell me there was nothing wrong with it – probably with FMJ ball ammo.
At any rate, the solution came from a discussion with my friend and FFL, Scott Igert, of Modern Antique Firearms, about the mechanics of the 1911. A lot has to come together correctly for a 1911 pistol to work correctly. In watching the pistol jam, I could see that it always hung on the pronounced shoulder edge of the Underwood 10mm ammo right on the edge of the chamber.
Any 10mm ammo that did not have that pronounced shoulder fed just fine. In doing some digging, I elected to do two things.
First, I polished the feed ramp. To do this, I fieldstripped the Big Rock and removed the barrel for easy access.
I then used my cordless Dremel with with a felt bob and Flitz polish to give the feed ramp a mirror polish.
Second, I used one of the fine rubber POLISHING tips in my Dremel to polish the edge all the way around the chamber. To be clear, I am talking about light polishing and not removing a ton of material. Do not use a sanding wheel or you may take off too much material in the blink of an eye. Take your time and be patient. My goal was to enable the 10mm case’s shoulder to slide over and into the chamber vs. hanging. My recommendation is to always go light, test and repeat as needed.
After the polishing, I then used some of the big 10mm cleaning Q-Tips called “RamRodz” repeatedly along with visual inspection to make sure all the grit was gone and not mess up the testing. Yeah –the RamRodz look goofy because they are huge and caliber-specific but they sure make cleaning easy.
For me, it just took one try – even I was surprised. Whatever the case was catching on was either gone or rounded over. The feed problem was solved – round after round cycled perfectly with no more jamming.
A few months after this I decided to sell the Big Rock to move on to other projects. I can’t say that Armscor’s support impressed me given I had one of their top of the line pistols. I gave them a very elaborate explanation of what was happening and they did not resolve the problem whereas a good talk with someone with a lot of 1911 knowledge, Scott, did. It definitely shows there are benefits to having a smart friend.
In closing, I will go back to a recommendation I always make. Before you rely on a pistol, definitely practice with the ammo you plan to use to make sure everything works the way you want. The Big Rock liked S&B FMJ, SIG HPs and further crimped Underwoods from Scott but not the factory-direct Underwood 10mm ammo until I did the above tuning.

As part of my foray into 10mm pistols, I picked up a Dan Wesson Bruin with the help of Scott Igert of Modern Antique Firearms. The Bruin intriqued me based on reviews and that this was a Dan Wesson pistol! I have liked Dan Wessons since the days they made the revolvers with exchangeable barrels. Not too long go they were acquired by CZ but the quality is still there based on everything I have heard. I sure liked their Titan but at $4-4,200, it was way, way outside my price range compared to the $1,800 Bruin.
Now I bought the Model 1880 10mm Bronze Bruin before my Big Rock because we found it first and the more I read, the more I wanted to get one. In my opinion it is excellently built. Here are the off-the-shelf specs:
Magazine Capacity: 8 rounds
Frame: Forged Stainless
Overall Length: 9.7″
Barrel Length: 6.03″
Width: 1.5″
Weight: 2.74 pounds
Trigger: Single Action
Front Sight: Tritium Fiber Optic
Rear Sight: Adjustable Night Sights
When the pistol arrived, Scott, his cousin Andrew and myself were all very impressed. It was coated in a ton of oil in a bag but the first thing we all noticed was how smooth it was – no grittiness anywhere. She slide and trigger were all so slick. The trigger is probably the best feeling of any pistol I own.
I field stripped the Bruin, wiped off the packing oil, lubricated it and took the pistol to the range. It shot like a dream. No problems of any kind with 180 grain S&B FMJ loads or either 155gr or 180gr JHP loads from Underwood. The Bruin handled everything smooth as silk and its weight really made recoil a non-issue. It’s there but it’s not a big deal is how I would describe it. Normally my carpal tunnel will act up and tell me when recoil is too much but I really just had fun. I’m so used to having to fiddle with guns that when one works just the way it should out of the box, it is a real treat.
Given the magazine capacity, I went ahead and bought two more magazines giving me a total of four mags. Interestingly, the website said they were out of stock but when I called their parts department they said they did have them and the gentleman I talked to mentioned that the website quantity onhand vs. actual wasn’t that reliable. So if you need mags, call them. Don’t just go by the website plus they have mags both with and without the rubber bumpter. I like the bumpers personally – they add a bit of weight to help the empty mags drop plus help protect the floor plate when they hit the ground.
One little detail I really like is the extended slide release lever. It has a little extended shelf that gives you a tad bit more leverage to push down and release the slide despite the heavy recoil spring.
Obviously I am a big fan of this pistol. I do have one con to mention – the Bruin has a distinctive angled front barrel plug that makes field stripping a bit tricky as you try and get things lined up. To be honest, I would chuck that angle and field stripping would become much easier. That is my only complaint.
At this point I am debating whether to keep the Bruin, the Big Rock or both, It may take me a while to decide 🙂 The Big Rock is a wicked brute and the Bruin is very refined. Both are better pistols than I am a shooter so more thinking is required. In the mean time here are some photos:
