For some reason it seems that the problems have been cropping up with newer guns. Plenty of folks have guns that are running perfectly, but a lot of folks are having problems. For example, a friend of mine has two M&Ps...one a full sized 9 and the other a 9 Pro. Neither one has ever had any problems. My Pro started having FTEs within the first 150 rounds.
I've checked the extractor, chamber, springs...you name it and there isn't anything I can find that seems suspicious. I got smart and saved the last case that was an FTE and it looks normal. Most times the case is extracted about half way and then the extractor is pulling over the rim and the gun tries to feed another. Mine has plenty of extractor tension (or so it seems) and the case rim isn't torn up from the extractor dragging over it....very odd. R,
