Sorry for the newbie question. I picked up my first Blackhawk (see previous post). It was made in 1995 and has the KXR-3 grip frame. The grip panels, which appear to be rosewood, are a little less than 1/16" sort of the bottom of the frame. I compared them to the panels from my 1974 Single Six, also with the KXR-3 frame, and they are the same length. Is there that much variance in the frames?
