I'm not a happy camper right now, I just got back from the range with my new PPS after the 67th round it froze, the slide is locked up and cannot be closed. I can insert and remove all mags but the slide release cannot release the slide. Up til that point I had no problems whatsoever. The 67th round locked the slide back. I used the slide release, everything ok, next shot same thing, next shot slide locked and unable to release the slide. Slide is frozen and I am unable to release it. Two other cops at the range unable to release. I have never seen anything like this. I guess I will have to wait till Monday to call S&W. Up till then it was smooth and accurate. Perhaps someone has come across a similar, is this normal?...
