The Pearce Frame Insert For GLK20SF/21SF is a simple, purpose-built plug designed to fill the open cavity at the rear of the grip on Glock 20SF and 21SF pistols. Molded from durable polymer, it uses a friction fit to lock into place, helping close off the exposed area at the back of the magazine well for a cleaner, more finished look.

This frame insert is ideal for shooters who want to keep dust and debris out of the grip cavity without adding bulk or changing the feel of their pistol. It installs without tools and does not interfere with magazine changes, making it well suited for range use, training, or everyday carry. Pearce Grip’s long-standing focus on practical, no-nonsense accessories is reflected in this straightforward upgrade.
