A large heavy caliber handgun, originally used to refer to a Colt Walker or similar sized revolver. Still in use today when referring to a big bore , long barreled handgun , typically a single action revolver. A hogs leg has quite the crook to it with the foot and since an old Colt blackpowder revolver somewhat resembles that form hence the term.
Tom Horn yanked that .44 hogleg out of Bill's holster and emptied all 6 shots into the ground right at Bill's mule.
