Gruesome dilemma.
I'm inordinately fond of revolvers. Of all makes I prefer S&W. Of those, I just love K- frames, especially 4" barreled ones.
On the other hand, that Colt is just one of those classy classics isn't it ?
I can't make up your mind for you, though.
For me in Belgium however, due to some really bizarre legal quirk, the choice would be a lot simpler : I wouldn't need any licence or permit to purchase the auto, as I would the revolver, so my being revolver-oriented notwithstanding, the Colt would get the nod.
