I would choose the ACP chambered revolver. I don't have occasion to shoot deer or hogs. I may well have occasion to shoot a two legged varmint and the 45 ACP cartridge has been doing that well for something like a century (smile).
I am fond enough of S&Ws chambered in this cartridge I had one built in a configuration S&W never made but should have...
a blue steel 45 ACP Mountain Gun.
