I have done so in the past. I've got a nifty rig for it, a double shoulder rig, built on the lines of the Montana Skeleton. The muzzles ride in little pouches about an inch deep, and there are little leather covered spring steel clips that hold the cylinders. The gun rocks out, and that's it. Quick as quick can be. Most people claim that a pair of 7.5" Super Blackhawks aren't concealable. They're wrong.
However, the more I got to thinking about it, the less that seemed like such a good idea. For one thing, although I'm plenty quick and accurate shooting two handed, if I were to have one hand disabled, and be forced to shoot one handed, it would change the whole dynamic. Second, even a short barrelled SA tends to be pretty long, and they aren't the easiest guns in the world to hang on to, if a goblin grabs hold of that long barrel. Third, they're about the slowest guns around to reload. Takes me about six seconds to recharge one, versus a second and a half for a 1911. Plus, the 1911 can be shot one handed, with no appreciable difference in rate of fire.
It's not a bad idea to carry a SA, after all, lots of folks carry J-frames, and they only hold five. But a big colt, or bigger ruger is a lot of gun to tote around for only carrying five or six rounds. They cite FBI stats that say most gunfights are over in two or three shots. Trouble is that there's no guarantee that the one you stumble into will be.
To my mind, carrying isn't about being cool, or different. It isn't about "what's the oddest, least efficient gun I can tote, and still possibly save my bacon when the chips are down?" It's about "what is the most efficient and reliable tool I can find for the job?" See my sig for more details.
To my mind, that's something that carrys a decent payload of a major caliber, is quick to reload if need be, and doesn't need to be thumbcocked between shots.
