I modified Bravos 3D GK1 Grip to fit my big hand. Removed the bottom little finger tab and put this piece of aluminum on the bottom, adding the perfect amount of length for me. I left the front of this addition extended some for my preference. I put a couple of screws and epoxied. I still might slip a rubber gripper over it, but It ain't too bad now. I also drilled and tapped a 10-32 hole for a sling stud. I like to have a sling stud and ring for hanging my pistols while in a hunting blind or on the wall of my shack.
