Glock kBs!
Yeah, and all Sig frames crack after 10,000 rounds, all HK firing pins easily break, you need at least $1,000 in custom work for 1911's to function, and all Beretta frames will explode and fly into your face.
It seems that any brand you get there's always somebody raining on your parade.
Glock .40s are used by LEOs all over this country and if it was a real liability there would be a big stink about it by now. kBs have occured even with factory ammo but they are so rare that driving on your highway to work is way more dangerous, IMHO. The vast majority of kBs occured because of jokers who used reloads beyond specs and now cry about it on forums like these.
Stick with .40 caliber FACTORY ammo that use new casings and all you need to worry about is hitting your target.
