Question about a specific type of jam(1911).

My Springfield 1911 Loaded has been running great except every once in a while it'll fail to eject the last round.
I thought it was just the mag (seemed to be specific to one in particular) but have had it happen with some other mags(o.e., Kimber, and Colt)lately.
Here's the deal- last round feeds like any other (completely flawless feeding so far :)). Last round goes boom and a mag change reveals that the mag won't drop free :( Upon trying to clear jam the little sh!t won't come loose :mad: So by this point I'm dead, playing with the stuck case :rolleyes:
Upon further inspection the rear of the case is wedged into the feed lips of the mag (kind of dug in-no apparent damage to lips though) and in doing so the case is tipped up and the slide crushes the front of the case. To release the case I have to push it down and forward to dislodge it from the mag.
The gun has had only approx. 400-500 rounds through it from 4 different mags.

Is this a handling problem on my part, or is it something more typical of a mechanical problem? OR, do these mags just suck in this way and are telling me to get Wilsons :D

Oh, if it helps the diagnosis any better, the follower does appear to be working the slide catch as it should because the slide is locked as normal.

If you haven't already, borrow some mags you know are functional. If those mags do the same thing, I'd send it back to Springfield.
 
To test if it's you or not, let someone else load different number of rounds into mags. Line them up and then you shoot them. Does the problem still occur on EVERY last round? Or are you anticpating the final round fired? If it still jams on last round, call Springfield and ask them what you need to do. My guess is they will tell you to return it to them.
 
I agree with ledbetter, find out your problem and fix it, but I would still buy Wilsons. They are truly better mags then the stock ones. I bought four of them for my 1911 and love them! I'm sure you will have no complaints when you buy them as well. Nothing feels better than a 1911, eh? ;)
 
It might be the mag, though I don't quite see how. It sounds like the extractor is not holding the empty case so it is dropping free and wedging itself into the magazine lips. Without the magazine in the gun, chamber an empty case and then pull the slide back slowly. If the case drops free before it touches the ejector and drops into the mag well, you have an extractor problem.

Let us know the results and we'll talk about "tuning" an extractor.

Jim, that sounds like what I've noticed while trying a slow slide pull. The case DOES seem to slide free onto the empty mag at about 2/3-3/4 out of the chamber. I would assume with an occupied magazine, the top round would support the case therefore not causing any malfunction and leading the case fully through to the ejector.
Is the extractor on a 1911 supposed to hold the case firmly? On some other guns I have noticed this to be the case.

Yes, a properly tuned extractor is supposed to hold (just barely) a loaded round in place.

Good luck

I wouldn't say "just barely", as it takes some pressure to push a case out of the grip of a well tuned extractor, but that site is a good one and I think that the extractor is where the answer is to be found, not in the magazines.

Thanks guys :D I just got back from a book store and Patrick Sweeney laid out the extractor stuff pretty good in his pistolsmithing book. From my impression this sounds like one of the more common problems that is easily fixed.
