I always wonder about that, also. Many sporting targets and magnas had them replaced by rubber grips over the years. I have a 1952 K22 4inch that lettered with targets. It was actually a promotional revolver presented to Jim Wilson,a pitcher with the Boston Braves by Smith and Wesson. Had I not lettered it, I would'nt have known about the grips or the history of the K-22.
