I just love this crap. ALMOST NOTHING can fire OOB. The design makes it impossible. I have never figured out where guys come up with this BS. the bulgingh cases are almost certainly from the bolt opening prematurely, before chamber pressures can be lessened. I have seen a S&W Mod 38 wadcutter pistol do this. We noticed a bulge in the cases as we fired it. No issues other than the bulge, but it wasn't staying locked long enough. No idea as to the cause in this case. My BIL also has a Glock that was a police turn-n that was also doing this. I looked at the cases. Same bulge. I noticed the slide was very easy to open and thought it may be the mainspring. We took it apart and the spring was bent a bit. He replaced it and good to go. I am betting there is something allowing the slide to open prematurely.
