Well, I see a lot of different brands having Kabooms - but the majority of them seem to be with .40 cal ammo. That is a high pressure round.
And reloads in that high pressure round! I don't think I've heard of a kaboom with factory ammo in a loooooong time.
Part of the reason the 40 caliber Glock kaboom stories are so prevalent is the Federal .40 load in the early-mid 90's, brass was very weak and kabooms were fairly common at the "path of least resistance". In the case of every single modified Browning linkless locking system that will be at the 6 o'clock position.
Glocks were pretty much THE .40 cal to get at the time, and so they got stuck with the bad rap. Glocks blowing up is just as common as any other gun, and in the vast majority of cases the ammo is to blame.
Unsupported chambers are not an issue...
Firing out of battery can be though. If your recoil spring is very weak, but your striker spring is fairly strong, the slide can not close all the way. Glocks have a little bit of play that they can fire in while being out of battery. This could be catastrophic in the higher pressure guns such as the .40. Easily avoided though with making sure to replace the recoil spring once and a while(Glock armorer I know says once a year if you shoot a lot).
Nice thing is Glock will send you a spring any time you need it!
