I personally know of two Glock G22 .40 cal issues. In both cases the magazine blew out the bottom of the gun, both guns locked up and both had bulged barrels. Both were police department issue and Glock replaced both guns with new pistols. Ammo was factory loaded 180 gr. FMJ, Federal if I remember correctly.

Every normal man must be tempted, at times, to spit on his hands, hoist the black flag, and begin slitting throats.
