A luger grip is generally held down on the frame by the screw at the bottom and to the extent it tucks in at the top. The grip scale is retained laterally by the contours routed into its back side, which snuggle into the openings on the frame beneath.

If the grip shucks around, it's because it's shrunk a bit and there's room for it to move before the protruding areas on the back encounter the areas on the frame that limit its travel. Shooting the gun applies forces that press the grip forward with each shot. This can compress the wood, which i turn allows lateral play/looseness. Artfully adding a sliver of wood or a bead of clear epoxy to fill the gap is the best approach, IMHO.

The "million dollar chip" results when the left grip scale is able to be pressed far enough forward that the wood behind the safety lever is pushed against the lever's shaft with each shot. It is also my opinion that his is far more often the cause of the chip than the touted careless removal of that grip panel. So make certain your left grip is good and snug, and that there's a whisker of clearance between it and the rear of the safety lever's shaft.
