.45 ACP for deer? Wow! Can't see even considering it personally. That's before I even get to the legality here in Ohio. Ohio requires straight walled pistol cartridges .357 or larger in addition to the minimum 5" barrel length. That rules the ACP out.
Actually a 1911 is legal in ohio .45 is greater than .357 and all mil spec 1911's have a 5-inch barrel.
Having said that, I don't think they are a good choice.
