This probably seems obvious to most here, but I'm gunna ask anyway. I've noticed that when texturing (checkering, stippling, etc.) is added (or even from the factory) to the frame of a pistol, the texture never seems to go up past about the half way point on the back strap area. Why is this? At first I thought, well maybe its to allow the gun to role in the hand (single action revolver style), but that doesn't make sense on an auto loading pistol, it would seem to me you would want as little role as possible in an auto. Maybe it’s to protect the web of the hand? Any insight is appreciated.
