Hey guys got a question about bullet setback.
I took a look at my glock 17 mag and saw some of the rounds were a little shorter than the others, upon taking some of the rounds out of the mag about 6 rounds were shorter than the others. these are PMC 9mm hollows. Are these too dangerous to shoot? I am concerned with things going KABOOM on me.
Appreciate the help If you can
