I'm looking for y'all's help in diagnosing a malfunction. I have a kimber 1911 , I know some will hate on kimbers but mine has been pretty much 100% reliable for over two years and around 15k rounds, that is having a weird malfunction. During the process of the slide moving back to eject, the spent case is not ejecting and the slide moves forward feeding a new round into the chamber with spent case still on the extractor right behind it. It started off with it happening once at two different matches. Then twice at the last match. I thought it might have been the recoil spring being a lil heavy for the ammo I was using Atlanta arms ( which it never did before).But switching to a lighter spring did not help matters and seemed to have made it worse when I went to the range today. I played around with my grip and tried to determine if it may be a magazine issue but didn't see a definite pattern. Ejector looks fine. I'm sure I'm not the first to have this problem. Thinking maybe the extractor needs to be re tensioned??? Any help would be appreciated and the first round is on me if your ever in my neck of the woods.
