The Lyman Grip Extender For Glock 20/21 is a slip-on magazine collar designed to bridge the gap between a compact Glock frame and a full-size magazine. Made from durable black polymer, it creates a more hand-filling grip surface while maintaining a clean, low-profile look that integrates smoothly with the pistol’s lines.

This extender is intended for shooters who run full-size Glock 20 or 21 magazines in compact or smaller-frame pistols and want improved control without altering the firearm itself. By filling the empty space at the base of the grip, it helps stabilize the gun during recoil and offers a more consistent trigger reach, making it well suited for range practice, training, and general defensive use. Lyman’s long-standing reputation for practical, shooter-focused accessories is reflected in this simple, effective design.
