Sidearms & Scatterguns issues with a springfield TRP 1911

[corey4]

i bought this about a week ago. i put 200 rounds thru it after i cleaned it up before the range trip. ammo was remington UMC, sellier and bellot, blazer brass.

this only happened on the last round, with all the mags, with all of the ammo.

i had the 2 mags that came with the gun, and my 2 remington R1 mags. i tried the ammo and mags in my R1 with out failure. if the round didn't get hung up like in the pics, then it would just kinda flop out of the chamber. the spent case definitely did not go flying like the other rounds.

any thoughts?

the 1st pic is obvious
the 2nd pic you can see where the mag was actually marring the rim. the spent case was actually getting stuck in the mag along with being smashed in the slide.
the 3rd and 4th are obvious as well.

Dented brass is about timing and ejection. Basically the slide and/or barrel is catching the brass as it ejects. Sometimes a different spring weight can change the slide speed but most likely you need to change the ejection angle so the brass makes it out without hitting the back of the slide. Extractor tension can help but, most likely, the face of the ejector needs to be tuned to get the right angle when the brass rotates out. I'd look for copper marks on the inside of the ejection port to see where it's impacting. If it's hitting the bottom of the port then you need the brass to take a more upward angle. If the brass is hitting the barrel hood then it needs to come down. I'd verify proper extractor tension first though to make sure the hook isn't loosing the brass wen it extracts.

I have the same pistol and love it, it runs like a sewing machine. I would call springfield and also email them the pics. They will get back to you quickly and get what ever problem this is worked out for ya. I've never heard of a TRP having issues. I bet it's an easy fix.

It's only occurring with the last round of each mag. Have you experienced this with all mags you own?

I'd say you need to increase the extractor tension. When a magazine has a round on top, the extracted case is running on top of that fresh cartridge. When the magazine is empty, the extracted case is falling down into the feed lips. The mouth of the case is rotating up enough to catch the forward edge of the ejection port.

shoot, i called earlier today and already have a RMA, but i just wanted to see what you guys said, hoping it was something dumb that can be a quick fix. kinda like, "my scope wont hold a zero!" well, did you make sure your screws are torqued?

g3, it did it with the 2 springfield mags, and my 2 remington mags. i aslo tired all the mags and same ammo in my remington 1911, and not one hiccup.

i forgot to mention, the extractor on my remington, you need a key, screw driver, something hard to move the extractor. on the TRP, i can wiggle it with my finger nail.

^ ^ ^ ShtrRdy nailed it - extractor tension, and why on last round - no support. ^ ^ ^

This failure is not a magazine problem, hence all mags function in other gun(s).

This is one of several reliability tests (load 1 round in magazine, chamber, fire) for 1911s.

A excessively loose extractor is not good either. Loose is OK but if it clocks / rotates Springfield will fit a replacement firing pin stop. I agree with the above post that it sounds like an extractor tension adjustment. My TRP also has a loose fitting extractor but no rotation.

i was originally thinking the mags were seating too high, the mag was actually grabbing the spent case on it's way out because of what shtrrdy said. no round for support to keep the spent case above the mag. just goes to show how much i know about hand guns!

i looked up on you tube how to tighten the extractor. it definitely doesn't feel loose anymore. in fact, it might be too tight now. i really had to sling shot the slide, i couldn't just let it go i normally did.

i did load up 2 rounds and hand cycled them. both rounds ejected the same way. what i didn't do was test this BEFORE i tightened the extractor...dammit, oh well.

if i can find time tomorrow, i am going to go run a box thru, only loading 2 rounds to maximize the testing.

thanks gentleman.

Had the exact same thing happen on my Range officer had the exactor tension worked on and no problem. I had about 1500 rounds thru it before it started giving me problems

...Springfield will fit a replacement firing pin stop...

what does that have to do with the extractor?

It's the plate that retains the extractor. If it needs adjustment springfield will fix you up if needed.

 

[corey4]

i ran 60 rounds thru it this afternoon. one case got smashed but didn't hang up, a few got deformed like in the pics, but nothing to write home about, and only one had a weak extraction that flopped out of the chamber. all of the others, probably about 10 of them extracted far away like they should without deformation.

thanks guys!

 

[ShtrRdy]

what does that have to do with the extractor?

A loose Firing Pin Stop can allow the Extractor to "clock" or "clocking". What his means is the Extractor is allowed to rotate in the Extractor Tunnel and therefore cause the extractor hook to be contacting the case at different angles.

 

[corey4]

so, if i keep running the gun like it, can i be screwing stuff up?

 

[Shoottothrill]

I would still send it in. They will diagnose and get it back fast, like brand new.

If it's damaging cases something is still wrong and it's likely the extractor fit and / or tension. There is a gauge to check it used with a trigger pull gauge to help adjust and set the correct tension. This is after you are sure the extractor fits the slide correctly and has the proper hook on it. If you are not sure how to adjust or set and measure the tension calling Springfield is a smart move.
