| Had an odd failure at the range. My Kimber Warrior fed a round ahead of the extractor and of course the slide would not close. I've never seen it do that before. Could this be a magazine issuse? Thanks in advance. |
Sorry I'm not good at explaining sometimes . It was 1 round went into the chamber and the slide followed without the rim of the cartridge sliding under the extractor. Imagine putting a round into the chamber and slowly letting the slide forward until the extractor just rests against the end of the round. Sorry kinda long winded. Thanks again guys.

BobCole: Off to the loading bench… I was only 14% right and 86% wrong! (1/7=14%) The last round in the magazine will push up behind the extractor on loading. However the preceding rounds 'pop' up under spring tension and jump forward of the extractor! I would guess with a strong magazine spring that even the last round could end up in front of the extractor too… From that I would conclude it is normal. If Unpierced was riding the slide forward on loading, it would not have the momentum to allow the extractor to force its' way over the rim. |

I won't begin to guess what happens with other 1911's, but with mine all the rounds slide up into the extractor as they come up out of the magazine. The extractor on a 1911 will ride over the rim of the case if it has to (for example if you hadn fed a round into the chamber) but that is not the optimum situation for reliability. If you want to test the concept, bend your extractor so that there is way too much tension on it and go shoot the gun. If everything else is running right, you will get failure to feeds with the round hanging up as it comes out of the magazine and the rim hangs up into as it attempts to slide up into the extractor groove. If the rounds are popping out in front of the extractor, I'd be concerned about one of two things: 1. The feed lips on the magazines preenting the round at the wrong angle. 2. The OAL of the cartrigdes allowing them to move too far forward in the magazine under recoil - again spoiling how the round comes out of the magazine. But that's just me and my 1911's. That said, if the extractor is not riding over the rim on the odd round where the rim ends up in front of the extractor, you might want to check the extractor tension and the shape of the extractor itself. |
I'd say there may be good advice given here. I would like to add that it may be best to use only factory ammo to test everything, even cheap FMJ ammo, IMO. |
I know you wanted to say it so I'll say it for you.  I've yet to see any 1911 that ALL case rims doesn't slide under the extractor. None are supposed to "pop" over the extractor.Dakota's advise is sound. Check the extractor for proper tension and make sure it is not clocking on you. |
