GrovTec GTHM244 Muzzle Thread Protector 1/2-28 x .590" Black Oxide - Fits Glock 17/19

The GrovTec GTHM244 is a precision muzzle thread protector designed to shield the factory barrel threads on your Glock 17 and Glock 19 pistols when a compensator, flash hider, or suppressor is not in use. Machined from quality steel and protected by a durable black-oxide finish, this one-piece protector threads directly onto the muzzle to keep debris, moisture, and powder fouling out of the critical thread area.

Cut with a 1/2-28 thread pitch and an outside diameter of .590", the GTHM244 is purpose-built for the 9mm Luger barrels found on factory and most aftermarket Glock 17 and 19 pistols. It threads on in seconds by hand or with basic tools and sits low-profile against the muzzle.

Whether you run a stock slide configuration or swap muzzle devices between range sessions, the GrovTec GTHM244 keeps your barrel threads clean and ready for the next accessory.
