Nice piece.
It's pretty much useless for deer hunting though.
Well, I suppose you can carry it for protection in case a buck foaming at the mouth with CWD decides to charge you and you wanna throw a whole clip at him, but you can't legally hunt with it if it only has a 4" barrel...
edit: You might be ok. It's 5.5" from pin to muzzle. I don't know if a 9mm cartridge is 1.5" long though so you still might be SOL...
