I just bought a Ruger 22\45 Mk III target pistol, the just released follow on to the Mk. II 10 shot, semi auto. I got the 4" bull barrel.
Shooting 1.5" - 2" groups at 25 yards with it. I think I could have gotten better, but I realized after cleaning it that the front sight was slightly loose and was wobbling a bit while shooting.
Bought it new for $249.00 here in the "we have a gun for everyone" state, Florida.
