I owned some really good ones in the past. Model 25 S&W, Colt MkIII, Ruger Blackhawk357. Those are all gone. Now it's a Ruger Speed-Six 357 with a 2 3/4" barrel. Fun to shoot and versatile.
The easy answer is: a S&W revolver. Although the model changes as frequently as I can arrange, my favorite is ALWAYS the latest one I've aquired. And my second favorite is the next one.
Gotta figure out how to put my guns picture on here but as of right now my favorite is the 686P with a 6 inch barrel, once things for sure is that this gun is ACCURATE "by the way this is my first revolver but I doubt Ill ever buy one and like it as much as I do this one.
I am in the minority here, but my favorite revolver is a four inch Ruger GP100 in .357 with fixed sights and a half-lug barrel. I like the blued one best but choose the stainless for its utility.
