The Permanent Beavertail can be applied to any Gen 4 or 5 Glock frame that accepts backstraps. We seamlessly incorporate the beavertail portion of the backstrap into the frame as a permanent fixture. Backstrap must be supplied by the customer for this modification. We alos suggest coupling this modification with the Razorback.
