GSR problem child

[sammy]

My brother has had a Sig GSR 1911 stainless with night sights for about 4 years. He had no more than 1000 rounds through it when we attended the 4 day pistol class at Front Sight about a year ago. The gun never had a problem untill the second day of the class. It started failing to feed and stove piping one every magazine. The gun went back to Sig and they replaced the extractor.
After it came back he only put about 20 or so rounds through it due to the ammo shortage. We went shooting yesterday, I chambered the gun and the hammer now falls to half cock every time. Pull back the hammer and it fires fine untill a new magazine is inserted and it falls to half cock again. The hammer stays back if a round is not chambered. It only half cocks when a fresh mag is inserted and the slide is dropped. With the mag full or with one it still falls to half cock. It extracts and feeds fine now so they fixed problem one.
The gun is out of warranty and I was wondering if their is anything I can check to fix it myself or does it need to go back to Sig? Thanks all, Sammy

Hey Sammy, I think sig will still fix even out of warranty. I think this was common problem with the GSR. Does his GSR have the "Manhole covers" on the slide?

Yep it does. I assume that is for the firing pin block. What have you heard? Is the hammer problem with the sear or what?

[louscamaro91]

I once had a Kimber with an external extractor that would do the same. Not to sure on the reasoning on why they do this. I'm not a big fan of the external extractor nor the extra safety the Kimber and Sig use. I had changed out the Sear and disconect spring(got bent) on my Kimber and it seemed to work fine. Hope it works out its not the end of the road for the Sig is it?

Before sending it back, might want to try and bend the sear spring just a bit to put more pressure to keep the sear from bouncing.

If the hammer hooks have been stoned (trigger job) they might have been cut to the incorrect angle.

if this is the case send it back. adding pressure to the sear through the spring is a band aid fix at best. Its like trying to fix a stripped bolt by trying to drive it in more.

please don't try to band aid it with spring pressure.

the original feeding problems sound like extractor tension which was an easy fix. the Sig external extractor isn't anything like the Kimber ones...the Sig extractors work.

too bad the hammer follow didn't come up at the same time....they would have just swapped out parts. it sounds more like a sear/hammer engagement problem than pressure and is usually addressed with a new hammer and sear. this isn't a GSR problem as much as a 1911 problem

just curious, are you holding the trigger back when you chamber a round? this will usually leave the hammer locked back and protect your sear/hammer engagement

When chambering a round my finger is no where near the trigger. The gun is not mine and my brother is not nice to his guns. He lives out of state and the gun spends most of the time sliding around under the seat of his F150 It will be off to Sig Monday. I am sure they will get it sorted out. Sammy

i'm sure they will and it shouldn't be too expensive

many things i learned as a child seem to have been lost with the passage of time.

the 1911 has many quirks that are not always applicable to other platforms. some have become legend and entered the lexicon without explanation, while some seem to have been forgotten.

something 1911 shooters of old always did was hold the trigger back while releasing the slide from slide lock or when chambering a round. you don't have to do it, but it does demonstrate a deeper understanding of the platform

If the gun was sent back to the owner with the sear spring having insufficient pressure then bending it to where it is supposed to be is not a band-aid fix. If you know what you're doing it may work, in this case my advice is to take it to a competent 1911 smith or send it back to Sig.

i would agree with this. a 1911 smith or Sig would be my recommendation too. a Sig 1911 would not be my first choice as a under the seat truck gun
