Continuing my Gonzo Grip Mod, left grip has the slot milled to line up with slot in modified magazine. Mine won't have the numbers or the offset slot to read them, or the offset mag button extension. It'll just show rounds in the magazine.
Here's a mockup of the grip and magazine with a couple rounds inserted...And chamfering the slot...I don't know if 'real' cartridge counter grips had chamfered slots, but it looks sorta nice...
Flipping the grip over and milling a relief for the polycarbonate 'window'...And also milling four small cuts for glue to hold the window from popping out...
