I imagine they're amazingly controllable, but what kind of stopping power on two legged varmints can you expect from a .22 Mag out of a handgun? If it holds thirty round, but you need three or four to stop a determined attacker, I'm not sure the math is that good compared to eight rounds of .45 ACP. Might have to get one, still the same though, just because they likely won't be legal to own for too much longer, for mere peasants, that is.
