The Pearce Grip Frame Insert For Glock Gen 4 Full Size models is a simple, purpose-built accessory that plugs the open cavity at the bottom rear of the grip. Molded from durable black polymer, it uses the factory lanyard hole for retention and sits flush with the magwell to help guide magazines smoothly into place while keeping dust and debris out of the frame.

This compact insert is ideal for Glock owners who want a cleaner look and a more finished feel without changing the pistol’s handling characteristics. It works with compatible Gen 4 and Gen 5 mid and full size frames while allowing continued use of factory interchangeable backstraps, making it a practical upgrade for range use, training, and everyday carry. Pearce Grip is known for straightforward, reliable enhancements that integrate seamlessly with Glock pistols.
