My beater guns are the two Glocks, 17 & 21. I can shoot a lot of rounds through them and they just keep on ticking like a Timex. I have shot just about every brand of factory ammo through the 21 and I've never had an ammo related failure with it. It's tough to practice tap rack & bang drills with these so I have to load snappers.
