Just joined a gun club and my first time shooting in a few years. I grabbed the PPS M1 because I had yet to shoot it. Cleaned it two days before and struggled with the guide rod trying to figure whether it was in or not and how to get it in, etc. Anyway I thought it was figured out. I'm at the range and I load it, first shot - nothing, next trigger pull - the bang, then nothing. Dropped the mag and the bullet seemed stuck in the chamber which I finally got out. Tried to load a different mag and when I released the slide, it didn't seem to close right. Gave up and switched to my other guns, Berettas. Can anyone tell me what may be causing the issue?
