Glock 30957 Backstrap/Beavertail Set OD Green Polymer

Fine-tune your Glock's ergonomics with the Glock 30957 backstrap and beavertail set in OD green polymer. Whether your hands are on the smaller side or you prefer a beaver tail grip profile for better control, this replacement backstrap kit gives you the flexibility to customize your pistol's feel at the range or in the field. Glock's modular approach to grip sizing means you're not stuck with one configuration—swap between profiles to find what works best for your shooting style.

The kit includes multiple backstrap options so you can experiment without buying separate parts. Two beavertail-style backstraps provide an extended grip profile that many shooters appreciate for recoil management and consistent hand placement, while two standard backstraps cover your baseline setup. The OD green polymer construction matches Glock's factory finish and durability standards.

Installation is straightforward: the kit comes with a trigger housing pin and a multifunction clip that doubles as a polymer punch, making backstrap changes quick and simple—no gunsmith needed. Whether you're building out your duty gun, competition pistol, or daily carry piece, having multiple grip options on hand means you can adapt your Glock to different scenarios or simply dial in the ergonomics that feel right in your hand.

Frequently Asked Questions

What Glock models does this backstrap kit fit?

The Glock 30957 is a GEN4 replacement backstrap kit. Confirm your pistol generation before ordering—GEN4 Glocks have a beavertail cutout and are compatible with modular backstraps, while earlier generations do not.

Can I swap backstraps without tools?

The kit includes a trigger housing pin and multifunction clip with a built-in polymer punch, so you have everything needed to change backstraps without additional tools.

What's the difference between the standard and beavertail backstraps?

The beavertail backstraps extend higher on the grip to fill the web of your hand, providing more contact area and better control. Standard backstraps maintain Glock's baseline profile. Both come in 2mm and 4mm thicknesses to adjust overall grip circumference.
