I'm a fan of the Ruger single action. Don't own any currently, but had a pair of Vaqueros in 45 Colt, an old Single Six, and one Blackhawk in 357 Max in the past. The Vaqueros and Single Six were a blast. I gifted the SS to the wife several years ago, since she's far more of a handgun shooter than I ever was.

The Max, on the other hand, was the only thing I have ever owned that made my ears ring with earplugs in. I took it out shooting ONE time, and promptly traded it off back at the same shop I bought it from. In hindsight, I wish I had hung onto it a while, given what they sell for these days vs what I paid for it back then.
