Glock 21 Kaboom
I shot a friend's Glock 21 and really want one for self defense. But I keep reading about these kaboom stories. The last thing I'd want during a self defense situation is my gun to blow up on me, and it'd be a bummer on the range too. People seem to disagree about what causes a kaboom.
What exactly causes a kaboom? And are there any documented figures/percentages to how often it happens?
The more I shoot the 21, am I playing the odds? Will it catch up with me?
