Just changed the barrel out to 357sig from the 40 and I was having trouble jamming. This is one of the IGB (supposed drop in) barrels which has been a pain in the @ss......Anyway I racked the slide to cycle some rounds and the bullet jammed again. I noticed the firing pin was sticking out and the shell caught up on it jamming the bullet in the ramp and half way down the chamber. I am going to have to dissasmble the slide but does anyone know exactly what happened here?? OK.......took the slide apart and answered my own question. The rod that contains the spring sheared off at one end so the spring pushed the firing pin forward. Case solved. Guess I'll be calling Steyr monday morning....... Anyone in particular to talk to.......????
