Problems with 10 mm TRP

If you can find the Sig ammo, I highly recommend it. I had some terrible accuracy out of Remington and Armscore in my Delta Elite. I switched to Sig and the shot placement tightened up like you wouldn't believe. It might be that the pistol wasn't fully broken in or something during the Remington and Armscore rounds but the difference was night and day and immediate. It went from a shotgun pattern down to fairly centered 2" at 15 yards just by opening a different box.
Was in hollow point?
 
Remington does that. I wasn't impressed by the local smith they had me send my rifle to. They eventually fixed the defect but they took forever and forgot to send my case back with the rifle. When they did find my case and send it back it was broken. I'd much rather the manufacturer handles everything so I can trust there won't be something funny happening.
Springfield forgot my case too when they sent the second gun. It was the case my Springfield custom shop, Custom Carry came in, from them 18 years ago. They were able to find it and send it back.

Hmm. Interesting. I guess there are two sides to everything. Evidently, someone didn't check out their local smith very well. :(
 
It was all 180 grain FMJ
Do you happen to have the muzzle velocity? I could check for ballistic stability.

Another thing to try is boresight it to see where that is relative to the sightline. One thing I've noticed while testing the TRP, along with other 10mm handguns is the sightlines of the slide, frame, and muzzle changes with every shot. Heck, even with the act of racking the slide will have an effect at 25 yards. While testing the TRP with more than 20 different loads, I found some hit right, some hit left, and some hit further down. It all depends on the weight of the bullet and its velocity.

Might be a long shot here, but do you happen to have a MantisX trainer? That thing is crazy sensitive.

I don't. It's Sig's Elite Performance stuff vs Remington green and white and whatever Armscor's basic stuff is called. I didn't have a problem with where the groups were, just how big they were. Then Sig fixed that.

Unfortunately, I don,t have any of that. I would like to check it with a boresight if I could find one to barrow around here. I agree with what you say about the sightline when in lockup. The locking lugs are really the only thing putting the barrel back in the same place shot after shot. This being a bushing-less gun might have something to do with it, if the lockup isn't consistent. I mentioned earlier that the first gun had excessive wear on the left side of the barrel and not touched at all on the right, where it contacts the slide at the muzzle end. You can see by my first target that the groupings are good. #3, I was actually trying to hold it tight, #1&2 was the first two 8 rnd. mags new out of the box, just making sure it worked and rough sighting it in. #1 didn't even put all 8 rnds. on paper.
 
I had no real problems with my TRP 10mm After extensive testing shooting it from a vise I found the grouping to be a little to the right and about 1.5" at 25 yards. I put around 20 different loads through it and all fed correctly, even that RIP ammo, heck, even the subsonic from Detroit ammo fed. I hate to be that guy, but most fail to feed can be tracked to the grip. My guess is the slide isn't traveling all the way back and just catching the round and striping it off. With the feed ramp already addressed, make sure the chamber is good can clean. Another thing to check is the ammo you're using. Have you tried a different brand? If the overall length of the round is a little long, it can jam. Perhaps look at the magazines, does it fail to feed on all mags, or just one?
I missed the first part of your question. The jamb would mostly occur from releasing the slide lock or pulling the slide back and letting it go, sometimes while shooting. It did this with all 6 factory mags. It could be the 1st rnd. or the 8th rnd. or somewhere in the middle. The round would completely clear the mag and get jammed between the transition of the throat and the inside roof of the chamber. Both guns did the same thing. The second gun has only done it a few times since getting it back for the second trip back from warranty work.
 
The transition area from the feed ramp into the chamber was sharp it would gouge and dent the case. You would have to remove the mag and push up on the half chambered round pretty hard to get it out. Most rounds were unusable after the jamb. Like I mentioned earlier, Federal,Armscor and Sellier&Bellot all had these issues. As of getting the second gun back the second time after them doing the work, it's much better, but once in a while, it will do it while releasing the slide.
 
I just purchased the Operator 6" 10mm. It's sad it doesn't have a full length guide rod, I thought that was standard with the TRP series. The worst part, is that the gun was jamming all the time ( failure to completely feed a round into the chamber) and was shooting really far to the left at only 15 yds.. I sent this gun back to them and they didn't even try to fix it, they just sent me a new gun. ... They didn't know that isn't allowed to do in New Jersey with out a permit. ... The 2nd gun did the same thing! So back it went. Springfield somewhat corrected this problem (but not totally) by radius, blending and polishing the throat and feed ramp into the chamber. The 2nd gun still shoots to the left, but not as much. As you can see by the photos, the rear sight shouldn't be hanging off the right side of the slide that much on a $1800 gun in my opinion. ( My Springfield custom carry 45acp. has fixed sights centered on the slide and shoots straight). The 10mm holds tight groups, there just off to the left. Has anybody else had a similar experience?

#1 first gun out of the box.
#2 sights moved to the right.
#3 moved further right

The exact same thing happened to my TRP OPERATOR 10mm. I was at a local indoor range (San Antonio TX) and I was charged $108 to remove the live round. It was the first magazine thru my weapon and it jammed. After the gunsmith cleared it, it happened again. I was furious and I even forgot to pick up my ID. I’m calling Springfield this coming Monday. This is NOT supposed to happen in a gun of this quality and price ($1800). I hope this gets worked out!

I'm having the exact same feed problem on my new Ronin 10mm. Did you get a hold of SA or find a solution?

UPDATE: After getting two additional magazines (both OEM) I did more testing by hand cycling. I tested Magtech, Federal, Blazer and Federal HST. In all 3 magazines the only ammo with feed problems was the Magtech. I inspected the rounds and I believe I’ve identified the problem. The cone of the bullet on the Magtech is a much sharper angle from rim to nose. All of the other bullets have a more rounded cone that is wider for longer before tapering to the snub nose. I think the narrower bullet in the Magtech is allowing the cartridge to feed further into the chamber before hitting the top and being pushed down. This is preventing the slide from being able to complete into battery. Just my two cents. Hope this helps someone.
 
Yea, not just one but two of the same guns did the same thing.Transportation laws here in N.J. have no provision for transporting your gun to a shipper, just to a range,FFL,your home or gun smith, specifically. You could argue that it is going to a gun smith by way of a shipper, but they "could" bust your balls if your in a town that doesn't like guns. I didn't want to void my warranty by doing the work myself. The throat,feed ramp and chamber was the same on both barrels, very sharp edges at the transitioning points that would dig into the brass, along the bottom of the case and drive the bullet head into the top of the chamber.
Just a thought, since laws are or could be strict transporting firearms to shipper there, possibly arrange with SA and LGS/gunsmith to have firearm shipped from LGS/gunsmith to SA negating your trip to shipper. Possibly lot of legwork, but less possible legal issues for you?

I had the same problems with Magtech ammo in my TRP. Sent mine in to get the ramp cleaned up and polished. It made a slight difference in feeding, but the Magtech was still problematic. No issues before or since with Sig, Federal or S&B, but it feeds smoother since the rework at SA. I guess I’ll stick with those.

I just took my brand new TRP 10mm to the range and had the same experience and I'm really unhappy! I expected a lot more from SA and for a brand new pistol to fail to feed and jam on it's break in trip is maddening for the amount of coin I dropped acquiring this thing. Factory S&B rounds pristine out of the box and both mags that it came with produced the same jam. The first thing that I noticed when I got it was that the throat was really tight and the mags were difficult to seat whereas my other auto pistols mags seat very easily with little effort and no resistance in the throat. I'll be calling SA on Monday.
 
Maybe just me, but I wouldn't accept having to have the rear sight hanging off the side like that from a $500 gun much less an $1800 gun. You can buy a lot of really nice, high quality 1911s in the $1800 price range.
