1907 Dreyse

The early grip frame on the left has the grip screw at the rear. The grip stocks are dovetailed and fit into tiny slots on either side of the grip. Serrations on the grip strap are a later addition. Note the screw just behind the trigger which is the sideplate screw from the left side of the gun.  The late grip on the right has the grip screw hole in the center and has two large holes cut to accept protuberances on the back of the grip plates.
