I was talking with one of the top performers in the league I shoot, and he suggested that I buy a rimfire pistol and wear it out if I want to improve. (He also suggested that I sell all of my handguns and only shoot a 9mm striker fired gun, but that's whole other story.) So I'm thinking about buying a 22LR revolver. The two handguns I shoot are a 44 revolver and a 9mm DA/SA auto loader. I figure the 22LR revolver will let me practice the long, heavy trigger pull of the DA on both guns, as well as the short, crisp SA trigger pull on the autoloader. (I never shoot the 44 in SA.) Which of the very few rimfire revolvers on the new market (I generally don't buy anything used anymore.) will adequately fill this role?
