I've had a S&W M41 for many, many years. It is just a fantastic pistol. I'd even go out on a limb and say that for a general use .22 auto, competition and field, it is the best ever made.
But my .22 that sees the most use is a Colt conversion unit mounted on a Gold Cup frame. It is accurate, never jams, and provides enough recoil to simulate a .38 WC thanks to the floating chamber design. It lets me practice with my .45 at .22 cost.
