Has to be .45 Colt of course and blued... and a Single Action to boot ... So the favorite 'right now' is the .45 convertible flattop on the left in following picture.
A clinger. When guns are outlawed, only outlaws will have guns. Single Action .45 Colt (Sometimes improperly referred to by its alias as the .45 'Long' Colt or .45LC). Don't leave home without it. Ok.... the .44Spec is growing on me ... but the .45 Colt is still king.
