The Vickers Tactical floorplate gives the shooter an enhanced gripping surface for ripping a stuck magazine from the gun if it refuses to fall free during a crucial reload. The larger plate works well with gloves and can even be hooked on a belt or holster in a tight situation. Plates are made of glass-filled nylon for high strength and impact resistance and have eight concave dots molded into the bottom for numbering or marking your magazines.
