I've got one. Just bought it last year.
I shot it with the factory sights, but recently put a Weaver mount on it with a Burris red dot. Now I'm thinking of getting some Quick Release Mounts and an ATN 2x6x40 lighted reticle scope. And eventualy, maybe even an ATN first generation night vision scope to go hog hunting with.
yeah, I can't make up my mind....
But I really like the look of the 1894CB in Colt 45. I wouldn't put a scope on it though, but maybe install a Williams FP receiver sight.
