Glock 30952 Backstrap/Beavertail Set OD Green Polymer - Fits G20/G21/G40/G41

The Glock 30952 Backstrap/Beavertail Set is a factory replacement module from Glock's Modular Back Strap System, allowing shooters to customize the grip circumference and reach-to-trigger geometry of their pistol. This kit is finished in OD Green molded polymer and is designed to fit the Gen4 large-frame duty models: the G20, G21, G40, and G41.

Glock introduced the modular back strap with the Gen4 platform so a single frame could be tailored to different hand sizes. Swapping the back strap changes how the pistol fills the palm and how the shooter's hand indexes high on the grip, while the matching beavertail extension controls the distance between the web of the hand and the slide. The set is a direct factory replacement, so it installs without permanent modification and can be changed back to the original configuration at any time.

Built from the same high-strength polymer as the factory frame, the pieces are dimensionally consistent with Glock's OD Green field of color-matched accessories. Whether you are replacing a lost or worn part or simply dialing in fit, this is the correct Glock factory module for the listed Gen4 large-frame pistols.
