I curious.
At what point do the loads go KB in a Glock?

I've done 10 plus loads in some of my 40 brass and no KB. I believe the KB is reserved for over charged loads.

I did KB a 1911 several years ago with a double charge of 5.7 grains of WW231 (11.4 gr). It broke the right grip, blew the plunger tube out, broke the hammer pin and blew the remaining rounds down into the mag due to an unsuppported chamber.

I re-peened the plunger tube, changed the grips and put a new hammer pin in. Works great. I don't know if a glock can come back as graciously so I'll be careful not to double them.

Any gun, 1911, glock, or what not with an unsupported chamber will KB with a double load. I'm fact, I'm going out on a limb here, I'd venture to say that any gun could KB with a double chatge.
