I've had a pair of the Cimarron Arms old style (1896-1940) frame SAAs in .45 Colt. I shot them a lot when I was into CAS and they both had trigger jobs to slick them up a bit. The only way to shoot a lot of those big cowboy calibers is to reload (unless you're rich). They've held up even better than I'd hoped.
I like the original style SAAs far more than the Ruger copies (which aren't even copies other than some styling cues. But when I got started with CAS I wanted to shoot guns as they shot them in the old days. My compromise was the second gen frame. Supposedly a bit stronger.
I never carry a round under the hammer and it was flat out not allowed at any of our matches - five rounds with an empty chamber under the hammer.
