GROVTEC Muzzle Thread Protector for Glock 17/19 Pistols

A threaded barrel on your Glock 17 or 19 is a gateway to suppressors, brakes, and other muzzle devices—but only if those threads stay pristine. The GROVTEC Muzzle Thread Protector for Glock 17/19 Pistols is a simple, effective insurance policy against damage when you're not running a muzzle device. Whether you're swapping between a suppressor and a compensator at the range, or just keeping your threads safe during storage and transport, this protector threads on in seconds and keeps your aftermarket 9mm barrel in shooting condition for the long haul.

Made in the USA from steel with a black oxide finish, GROVTEC's design is built to handle the job without fuss. The protector uses a 1/2x24 thread pitch—the most common spec for 9mm Glock builds—and fits aftermarket barrels with a .641" diameter. It's the kind of low-cost, high-value accessory that serious Glock shooters keep in their range bag or on their nightstand gun when no other hardware is mounted.

If you've invested in a quality threaded barrel for your Glock, protect that investment. GROVTEC thread protectors are the standard choice for shooters who understand that taking care of small details keeps firearms running reliably for decades.
