At the range, every single time, somebody will come by and say how difficult it "would have been to stay alive shooting one of those."
Especially seeing me fumble with the caps and all. Well, it's the truth. However, the alternative was a single shot something, or a knife or a large stick or rock. A percussion revolver was the Ipad of its day, a technological wonder.
So, sure, comparing cap-n-ball to a Glock isn't a fair comparison. However considering the alternative in 1858, I think I'd chose a Colt Dragoon over a singleshot/knife/stick/rock combo. I might even chose a Colt Dragoon anyway.
