I shot my 17L and probably 15 out of 100 rds had trouble ejecting. They weren't stovepipes but the spent case would just jam the slide open lengthwise. Looks like the slide is going all the way back because the next round is partially fed, and looks like it would go into battery if it weren't for the spent case jamming things up. My theory is that standard pressure loads are not pushing the heavy 17L slide fast enough, to eject forcefully. I read elsewhere where a 17L owner said NATO and +P worked fine, but not std pressure. What do you guys think the problem is?
