Almost all makes and models of weapons have, at one time or another, had a KB. There are a lot of Glocks out there and yes, some have KB'ed. Most of the problems have been traced back to the ammo. I personally had a S & W revolver KB on me. If you use good quality ammo you shouldn't have a problem. Early versions of the 22's had a few problems, but those issues have been addressed. Alot of it has to do with the ballistics of the .40 cal. The 22 Gen 3 is not any more dangerous than any other semi if fired responsibly. Before you buy any weapon, try a few at a range, if possible. If not, try holding a few different ones at the store to see what one feels the best in your hand. Only you can decide which one is the best for your needs.
