I have a friend who recently experienced a kaboom in his G 21 45 acp Glock. Fortunately he was not hurt; but it did scare him. The cause was a wrongly loaded 45 acp round. Bothered him enough that now he jokingly refers to his Glocks as the Austrian hand grenade.
Now I have heard of kabooms with 40 caliber Glocks and 45 caliber Glocks; but never with a 9mm Glock 17 or 19. Has anyone heard of a kaboom with a 9mm?
I don’t reload and personally would not use any reloaded ammo in my Glocks. There is a well known chamber issue that has been discussed widely.
I’m sure there are folks who do it well but I just won’t take that chance. I heard about the reload issues before I ever even owned a Glock.
