I just finished watching "Lonesome Dove". Capt. Gus McRae used his Remington 1858 as a weapon when he smacked the bar keep up along side his head for being rude to Capt. Call! And he didn't even need to pull the trigger for it to be an effective weapon!
Maybe it was a Colt 1851? Not sure, but it was a good weapon in that situation, regardless!
1847 Walker Colt actually.
I'm amazed that we have a five page discussion on this. Unless it's loaded with rainbows and sunshine it's a weapon.
