BTW, is it possible that the OT stocks are Coke grips? They are the diamond type, without numbers on the inside to match the frame. The reason I ask is that they are MUCH more comfortable in the hand than other OT grips I have handled. They may have a slight swell to them that enhances the feel, but if so it is quite subtle.
