I bought a used Kel-tec p3At and it's having a lot of FTE problems. A lot as in every single shot fired FTE. The spent case remained in the barrel. It looked like the extractor failed to grip it and fling it out. So what I tried is to put a death grip on it. I also used heavy push/pull force with my shooting hand and my support hand. Only then it successfully ejected, most of the time. It is a used kel tec and between the original owner and me, we probably shot it at least 75 times. The original owner actually sent it into keltec to repair a broken extractor. They gave him a new one and polished the feed ramp for him. I cleaned it meticulously and even replaced the extractor with a new one. I made sure the screw was tight, tried 3 different brands of FMJ ammo, and tried 2 different magazines. Nothing helped except when I had to use a strong push pull grip. I had to use a very strong tension. I've shot many other semi-auto handguns before, and I never had a problem with them. Also, the severe pushing I had to do made me shoot lower. Who knows, maybe my shooting technique sucks. But I'm a little worried about the reliability of my kel tec since it's main purpose is to be a defensive pistol. Sometimes in a defensive situation, your grip will not be picture perfect, and it should function reliability regardless of how your grip it. So what are my options now? Do you guys have any suggestions on how to fix the problem? Will Kel Tec look at my pistol even though I'm not the original owner? Thanks.
