Who This Is For
This grip extension is ideal for Glock owners who carry or compete with the Model 20, 21, 29, 40, or 41 and want a simple, no-tool upgrade that adds rounds and improves hand purchase on the grip. It is especially useful for shooters with larger hands who find the factory floor plate leaves their pinky unsupported, or for anyone seeking a modest capacity boost for range use or home defense.

Frequently Asked Questions
Will this extension work with my Glock 30 or 10-round magazines?
No. This Pearce Grip extension is designed exclusively for high-capacity Glock factory magazines in the M20, M21, M29, M40, and M41 models. It is not compatible with 10-round M20 or M21 magazines, and it will not work on any Glock M30 10-round magazines. Always verify your magazine type before purchasing.
Does this extension require any tools or gunsmithing to install?
Installation is straightforward and can typically be done without special tools. The extension replaces the factory floor plate on compatible Glock magazines — simply disassemble the magazine per Glock's standard instructions, remove the existing floor plate, and snap the Pearce extension into place. Most shooters complete the swap in just a few minutes.
Is this product legal to use in California?
California restricts magazines to a maximum of 10 rounds. Because this extension is designed for use only on high-capacity Glock magazines and adds two additional rounds of capacity, it is intended for use in states where higher-capacity magazines are permitted. California residents should consult applicable state and local laws before purchasing or installing any magazine capacity-increasing accessory.
