Without a doubt it is my Ruger blued .45 Flattop convertible. Internals were worked over by the late Bob Munden and it shoots like a dream. The medium size frame is just right for .45 Colt. Hardly ever leave for the range without it.
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.
