Glock 30819 Backstrap/Beavertail Set Compatible w/ Glock 20/21/40/41 Black Polymer

The Glock 30819 backstrap and beavertail set gives you a way to tailor the grip of your full-size Glock 20, 21, 40, or 41 to fit your hand better. Whether you're working with a naturally larger grip or just prefer a more snug purchase on your gun, swapping in the right backstrap can reduce reach to the trigger and improve control—especially important for fast, accurate shooting in the field or at the range. This is factory Glock OEM hardware, made to the same standards as the pistol itself.

Glock backstrap and beavertail components are straightforward to install, and having the right fit matters more than people often realize. A grip that matches your hand geometry means faster target reacquisition, less hand fatigue on longer range sessions, and better consistency from shot to shot. The black polymer material is durable and requires no special maintenance beyond keeping your gun clean.

If you own one of the large-frame Glock pistols and haven't customized the grip yet, this is a simple upgrade that pays dividends. OEM parts also mean you're not guessing about reliability or fit—these components are designed and tested by Glock to work with your gun, with no surprises.
