At Glocktalk I was reading that some Glocks have blown up because a Glock can fire when slightly out of battery (Slide not totally locked closed). The moderator said he personally witnessed a Glock 21 blow up using factory 45 ammo. Its all news to me. When I go to the range and watch what kind of firearms give problems it never seems to be Glocks. I have never heard of a Glock actually blowing up. I am 55 years old and the only gun I ever heard of this happening to was a revolver that had fired a squib load that lodged a bullet in the barrel then when a non squib was fired after it the barrel was bulged and ruined. Maybe others have heard of these problems?
