Here I am!
Yep, all guns can and have kBd, that's for sure! Saw the remains of several Glocks and a Walther P99 that did it at the local indoor rental range w PMC factory ammo, the wimpy 165g FMJ at 985 fps. Damage ranged from hairline cracks in frames to ruptured bbls. Obviously bad ammo, but... why are they messing up the 40/45/357 ammo so much more than the 9?
OTOH, it sure does seem like the Glock 40/45/357 do it more often w more damage w factory ammo than the Glock 9s do or ever did, even w LE +P+ and mil spec ammo. So it could be the guns too?
OTOF (foot), ditto the other guns when comparing 9 to 40/45/357?
So...
If I can accept that Glock 40/45/357s may be closer to the edge than the Glock 9s, I can accept they may also be closer to the edge than some other guns for similar reasons, whatever they are.
Looking at a USP 40/45/357 bbl comapred to a Glock, not hard to accept the thicker chamber walls and additional case support might give me more margin for error before I go over the edge?
Still plenty of room to argue that makes the Glocks different, not defective, nor dangerous.
Viva la difference!?
