You can use it for elk, deer, bear, groundhogs, coyotes but not with full metal jacket ammo.

Ricki, As a responsible conservationist I would not use a 45 ACP weapon to attempt to harvest any game larger then small game regardless if legal or not. To make an ethical clean harvest you need the correct caliber, type, power and size of round. 45 ACP is not a game harvesting round.

sorry 45 ACP is not a hunting round It may be legal but it is not humane to hunt with a underpowered round it would be ok for groundhogs and maybe coyotes but never deer any larger game
