I just got a great new Model 990 Tracker .22LR revolver. I went to the range and loaded a full cylinder of nine .22LR rounds, and let her rip; very accurate, with a great trigger, and every round reliably fired.
Revolverfan, Feeler gauges aren't very expensive. These are typical.
Looking to add a rimfire handgun to my arsenal. I have been looking at the Ruger 22/45 Mark 3. Seems like a really nice pistol. But I admit, I'm a revolver guy. Don't like the idea of loading magazines with the 22/45, and definitely don't like the idea of cleaning the 22/45!!
