My 1911 has problems for some reason, that it will not fully return to battery, after firing. I replaced the stock recoil spring with a Wolff OEM spring, and it worked great. My buddy was shooting it, and he said after around 150 rds, it started doing it. There was proper lubrication, and he was using either Wilson or Novak mags. Anybody have any suggestions? I would guess it has between 450-600 rds through it. |
| Believe or not I would first check the extractor. If the extractor has too much of a bend or hook at the end it will not allow a fresh cartridge to slide up the breech face. This will cause the pistol to not go into battery or lock up. This is a common problem on less expensive 1911's. |

Hmm, I never thought about the extractor. I've got a couple GI ones laying around. I will get them swapped out. What exactly do you mean by a firing pin safety? It has the ambi, slide mounted safety, and the standard bearver tail safety that your hand grip depresses. |
Yours does not have a firing pin safety , so don't worry about that. 1911Builder is right. It's most likely your extractor. Even if you swap out with a new one, it still needs to be tensioned properly. Try it out, and if it still does not work, I'll try and find an old thread regarding this where there are several explanations onhow to diagnose and fix this problem. Also, you are not really having a failure to feed, per se. You have a failure to return to battery. A failure to feed means a round is not going into the chamber. A failure to return to battery means it is horizontal in the chamber, but the gun does not close to the locked postion. At least, from your description, this is what it sounds like. A few other things to consider wiht a failure to return to battery are these: -You might have an overly tight barrel bushing causing springing and failure to go into battery. This is highly unlikely in a loose fitting ARMSCORP. -Your bottom barrel lugs might have been left too oversized during fitting, causing drag on the slide stop. Again, this is highly unlikely. -Your barrel hood might be oversized on one side, causing the corresponding relief cut in the breechface area to catch on it. This is much more within the realm of possibilty on your gun. -You might have a faulty disconnector that is sticking and dragging on the slide, though again, it;s highly unlikely. Check the extractor first, then the barrel hood. Let us know what you find. In the meantime, I'll look for that thread with all the extractor info. ETA: the thread I was looking for was trashed or deleted. |

I know you said it was "properly lubed" but does that include a field strip and cleaning? Just trying to help. good luck |

I am the aforementioned 'buddy' The pistol was cleaned prior to shooting about 200rds one afternoon. About 150rds into it the probs started. Before this I had field stripped it and cleaned it out and lubricated with LSA. Switching to a more powerful Wolff spring really helped. Ill change the extractor this week and see what happens. |
No offense, but if the round starts into the chamber, and the barrel just does not lock up into the fully forward slide position, then it's definitely not the lack of a feedramp polish. In a failure to feed it might be an issue, but even there I would doubt it. ARMSCORPs have a properly throated barrel throat, and the biggest issue I see with those are over ramped frames. If it's a failure to feed, you might address the throat and feedramp, but a failure to return to battery is something else. |
