Sorry to hear you're still fighting your jam issue! The Aftec worked like a dream on one of my STI's, and a fair amount of bending/filing took care of the same issue on my backup STI (both identical TruBors). I did load a bit longer when I was struggling with my jams to see if that would help (it didn't) and never shortened it back. The STI's are back to eating everything without issue. Did you do any fitting with your Aftec? You might still need to adjust it a bit. For what it's worth, I only installed one spring on the Aftec initially, and since it works I never went back and played with adding both/fitting/etc.

Just an update. I received an Aftec extractor and watched a few YouTube reviews of it before putting it in. I opted to install without using both springs (I left out the one closest to the muzzle). The instructions mention that fitting may be required here and there, but I thought I'd try it out without doing anything. There was a local match yesterday and I arrived early to see if the gun would cycle and put 2 140mm mags through it without issue. Then proceeded to shoot the entire match without a single malfunction. I think you guys nailed it! THANK YOU ALL FOR YOUR HELP!!!! That was the first match in a long time without a failure.

Well, it couldn't hurt. Just ordered an Aftec from Dawson Precision. I'll also see if I can get the OAL a little longer and see if it helps until the Aftec arrives. Appreciate the help!

I wonder if I can go much longer. The 115's don't have that much left in the case when I get them out there. Missed you last weekend. Get tired of beating everyone?

I think you just made my day. That would explain the issues exactly. Would you suggest trying to get the EB or just spring for the Aftec? Thank you for the post!

I have two identical STI TruBor 9mm Open guns and one of them has always had the occasional jam (see picture below). It started getting worse and would jam once per stage last time out. It has happened with both STI and MBX magazines, all fairly new. I've tried 8 - 11 lb recoil springs. The ammo is all tested before shooting in my Hundo. Using a Lee U-die/seating/FCD. Everglades 115 JHP, but has had the same issue with Montana Gold 124 JHPs as well. OAL is around 1.158ish. This pistol has about 3k on it. The other TruBor has around 9k on it, and jams occasionally, too. And for what it's worth, I've recovered the rounds that jammed and they look find, and case gauge fine as well. Any advice/tips/things to investigate would be great! Loosing my mind. Thanks!

If you have trimmed the spring under the detent ball, try putting a new spring in and see if that corrects the index issue. There are better ways to correct the powder spilling problem that don't result in poor indexing. This was my primary issue and replacing the spring pretty much took car of it.

You are not wrong. In fact, I had the primer punch back out and cause an issue which gave me the idea to shim it out. I think it's a tolerance stacking issue with my press, the thickness of the primer, the depth of the case's primer pocket, etc. But I would sometimes need just a bit more throw to get the case into the proper position in stage 1. Adding a small shim still allows me to very solidly seat the primer, but gives me a bit more margin. I'm sure it's a bit of a bandaid for other issues, but every little bit helps.

Yes, it was the primer punch. Sorry, I forgot the name of the part. You can try unscrewing it a couple of turns and test it to see if it's worth doing anything.

I used a part of a snap ring. You could stack some small washers in there if you find some that'll fit. Perhaps form a paperclip around a bolt and use that. It didn't take much to give me a little extra throw.

Like I mentioned, I started having the same issue and it was driving me crazy. I poured though all of the posts here about folks having the same problem and checked all of the things people suggested. I'm happy to report that I did wind up fixing it. It was several things in aggregate/tolerance stacking that was causing my stage 1 issue. The biggest single issue was that the two bolts that fasten the shell plate holder on top of the ram, had come loose. I had gotten the alignment tool and used it several years ago and got it as close as possible, but it still rubbed a bit, but there was no more adjustment. It was good enough, but the screws did loosen up over time. I'm glad I checked! I realigned it and added a generous amount of Loktite. I put a piece of brass in stage one and clamped my tool head in place (I used the Uniquetek kit to thread/clamp my toolhead to the press). While the case was still in the Lee U-Die, I loosened and tightened the lock ring of the die. Cleaned and lubed it all, and she's running good as new, and only the occasional hit on the sizing die. One other thing that I'll mention that I did that no one else did, is that the little spring loaded primer seater doo-dad would seat the primer and kept the handle from moving any further back, which also kept the case from being pushed all the way into the shell plate. I used a ring to shim out the primer seater assembly and it gave me a bit more pressure on the case. Anyway, I hope you get your press running, too.

Did you ever figure out what the issue was? Having the same thing with my 650.

I clean all my fine glass with Kimtec wipes. https://www.amazon.com/Kimtech-Science-KimWipes-Delicate-Wipers/dp/B00F462ZJY/ref=mp_s_a_1_3?ie=UTF8&qid=1545539934&sr=8-3&pi=AC_SX236_SY340_QL65&keywords=kimtech+kimwipes&dpPl=1&dpID=516k4NeWnXL&ref=plSrch No lint/dust. I keep a wad of them in my parts kit.

Just a quick update. I started with the easy stuff first and in the end, it only took a couple of twists on the over travel screw to get her running without issue. Thanks for all of the help and suggestions! I truly appreciate you guys taking the time to help me out.

Thanks for the tip! I have made some adjustments and hope to get out to the range soon to test it out. Appreciate all of the help.

What fun is that? I'd like to check the low hanging fruit first and see if it's something simple. I find that I learn more when something doesn't work properly and I have to work through the process to fix it. You guys are great at providing ideas for me to explore and I really appreciate it!!!

Here's the kit I used: http://www.1911store.com/tunedtriggergroupbcg-proseries.aspx Any idea on how much side play I should check for? Thank you!

OK, just tried it and the hammer doesn't follow the slide. I tried it about 25 times and it stayed cocked every time.

Sounds possible. Any idea how to check (besides going back out to the range to test fire)? Anything I can measure to verify? I'd love to know for sure so I have confidence in the gun. Thanks!!!!

Just looked. Look nice and tight. Thank you for the suggestion!

One other thought. I recently noticed that the trigger was moving too far back and adjusted the over travel screw. Any chance that could cause this issue? Thank guys for helping out a 2011 noob!

It doesn't seem to ever go to the half cocked position. I'll fire a couple of rounds and then the gun will stop because the hammer is fully against the firing pin. I'll check this though. Thanks!

Yep, I did mean hammer. I guess I was more tired than I realized when I posted that. Thank you for asking!

I have a 9mm Trubor that I recently got as a backup gun that only has a couple hundred rounds through it. It has a Brazos trigger kit that was put in day one. Today I was shooting it and the gun would stop because the hammer wasn't locking back. I pulled the leaf spring and bent it a bit thinking it might need more pressure on the hooks, and although it helped a bit, it still wasn't great. Any ideas on what might be going on with it? Thanks, all!

Thanks guys for the suggestions. I did watch most of the Atlas videos already, good suggestion! Also found some good videos on the basics. I guess I would like to get more "gunsmithing" savvy and know how to work on things at a deeper level. I see AGI has some videos for sale, but not sure if those would be going overboard. I just bought a gunsmithing book on amazon that looks good. It had good reviews and the Kindle version was under $5. https://amzn.to/2PuvsEd Thanks again everyone for the posts. Keep 'em coming.
