Let me clarify my question. The gun would be used during the gun season for deer and thats why I'd need a 6" barrel, to meet regulations.

Thanks for the info and its great to learn while researching something.

I would have never guessed these pistols could inflict that type of damage on the user by placing your hand up forward. Could a .357 do damage like that as well? The reason I ask isI had a .357 twenty years ago with a 4" barrel that I carried for backup while bowhunting for elk in grizzly country. Honestly I couldn't hit the broadside of a barn with that. Its been a while ago and I gripped it with two hands, both probably wrapped around the trigger/guard.
Secondly, this gun, the 460,can shoot the 454 casull or 45 colt as well as the s&w 460. Or am I reading it wrong on S&Ws website and it comes in those calibers? And is 45ACP the 45 colt, got this from cabelas ammo catalog.
I've not actually been to a dealer yet looking, I'm researching on here first to learn as much as possible first.
Thanks
sorry for the long post
