Ruger and Magpul collaborated to make a real decent Glock pattern 9mm. People are liking them and my buddy carries his around the ranch. Using 8 oz "Whiskey" Buttero bonded and stitched to 5 oz black Minerva inside. The goal is to only have the top grain touch your piece. Top grain wipes down clean and doesn't pick up dirt and debris that can mar the finish on the slide. After wet molding, and drying the pistol snaps in place securely.
