Screw spacing is different. You would wind up with a slot instead of a hole. I built mine, I talked to John about making them a production item and it's not high on the priority list.



I originally wanted to have it long enough to go to the trigger guard screw and past the front of the recoil lug. But the piece of AL I had on hand worked. Next one I build will be full length and have the drop box bottom metal integrated into it.
