Springfield TRP jam

[sephknite]

Hey all. I just took some time to clean my TRP Operator after the first 100 rounds at the range yesterday. After some cleaning and reassembling the pistol, I found that some of the dummy rounds I'm using are getting jammed.

What happens is I manually load 3 dummy rounds into a magazine and just pull the slide back to make sure they load. On quite a few occasions, the 2nd or 3rd round is fed into the barrel, but the slide does not contact fully with the barrel--basically a very visible gap. I'd have to eject the mag and pull the slide back to pop the round out of the chamber. I'm wondering if I reassembled it wrong or didn't put enough Break Free CLP into the parts. Any advice?

I'm using CMC PowerMags and Shooting Star mags. Maybe I should try the factory mags too. Wondering if that's the problem..

It could be too little lube but it's more likely that hand cycling isn't giving the same amount of force that shooting the gun will. It's still new and tight and needs to be shot to mate all the metal to metal contact surfaces.

Take it to the range and see if it has the same problem before you decide to do anything to the gun. And......lube it up real good, especially in the slide tracks and the track under the frame rails.

(I am also assuming that you put the recoil spring back on the guide rod the proper way.....with the closed coils next to the guide rod head.)

Yeah, I'm thinking I did too much wiping, not enough oiling/lubing. For 100 rounds, it got quite dirty. Dirty, Dirty Winchesters!

Right now, my thumb/fingers are in pain from the Slide Stop reassembly and spring-pushing action for the guide rod, but I'll do the slide/frame track lube like you suggested. The recoil spring/guide rod, I believe I put them back properly. If necessary, I'll take pictures of the guide rod/housing reassembly and (hopefully no more) of the jammed round. Thanks, Kruzr.

This is why I like the short guide rod with spring plug on GSR Revolution
I can field strip the pistol without using any tool.

What do you think that SIG invented short Guide rods? I don't think so. 1911 makers have moved away from them to help the gun cycle better. Please tell me what this thread has to do with field stripping? And if you are "field stripping at home (or anywhere else), how difficult is it to use an Allen Wrench? I am confused by your reply to this thread, what was the purpose? If you are trying to brag about the virtues of the GSR, I can easily put a stop to that, just Google "SIG GSR problem" and a laundry list will soon appear.

On my TRP operator the spring is not directional. To strip it you need a small pin to keep it compressed then tap it out from the front of the slide. When new it was difficult to put the rod/spring assembly back fully into the slide,make sure you have them seated all the way and your problem should be solved. I had to file a little on the collar where it enters the slide to make this possible without a excessive force. Good luck

?? All 1911 recoil springs are "directional." The closed end must be at the guide rod head or the compression force of the spring differs. Less spring is used if you put the recoil spring in backwards. This will cause many guns to short stroke. I find backwards springs causing problems about once a month at the range. When I find the problem, I always hear..........."I didn't know it made a difference." It does.....

I don't understand why SA uses that funky two part guide rod. They could easily use a one piece that is short enough to compress the open ended spring plug with your thumbnail like you do on a Kimber. No tools required.....no allen wrench, no bushing wrench.

With respect to cycling.........a FLGR does nothing. Measure the diameter of the spring and then measure the space in the spring tunnel and dust cover. The spring cannot deflect more than about an eighth of an inch. There is no way it can hang up and cause cycling problems.

That being said, I have FLGR's in about half my 1911's. I switch back and forth when I get the bug and there is absolutely no difference in the functioning of the guns.

FLGR's are popular just as Teal colored cars were in the 80's...........they are in vogue now. They do add weight and that helps with muzzle flip but a proper grip and stance and spring tuning will do more.

TRP operators don't have FLGRs, they have the reverse guide rods? I think that's what they are called. It's because of the bull barrel. FLGR take down is easy compared to the reverse plug set up. It would be impossible (simply wouldn't fit) to put in backwards on a TRP operator.

Well, I guess that's why they use the two piece GR. (I don't keep up with the SA line)

A bull barrel uses a reverse shoulder plug. A reverse shoulder plug does require the spring to be out of the way for the guide rod to be removed from the slide. This is done by using the two piece, or using a tool to compress the spring and plug so it can be lifted out.

Update: I've done some super-heavy lubing on my TRP last night. I got the hang of stripping and reassembling..sorta.

At any rate, after drenching all the parts with CLP, it seems to be working fine now. I paid a lot of attention on the guide rod bushing/barrel and the top portion of the slide/barrel contact areas and just made sure they had a good amount of CLP. After reassembly, I tried all my mags with 3 dummy rounds and they all went through fine, with a few exceptions where the dummy round got stuck because I wasn't pulling on the slide hard enough--hands were way too oily.

its clearly defective and proabably there is nothing you can do about it....but don't worry, i'll help you out and pay you 500 cash for it so you can have some money in hand for your next gun.....

Awww...1 day late. Hehehe..I fixed it. I could have had $500! Sorry, guess I gotta keep it.
