So I've have my pt1911 for a couple years now and every once in a while I'll have a problem with a round not feeding properly. I've figured out that what's happening is the round is getting stripped of the top of the mag and the rim is not sliding up behind the extractor claw. The round feeds up into the chamber, but the slide doesn't close all the way because the extractor is still riding behind the edge of the rim. Again, it doesn't happen very often, but that's still too much. It had happened with several different kinds of ammo, and before you say it, I'm pretty certain it isn't a limp wristing problem. I was wondering if anyone had an idea as to the cause of this problem, or more importantly, a solution!
