This Thread Protector 1/2 x 28 in Copper is a functional and aesthetic upgrade for your Glock barrel. Designed for 9mm and .357SIG barrels with the common 1/2×28 thread pitch, it screws directly onto your muzzle threads to protect them from impact, debris, and cross-threading when a muzzle device is not installed. This essential Glock part prevents damage to your valuable barrel, ensuring threads remain in perfect condition for when you attach a compensator or suppressor. The distinctive knurled thick spiral pattern in solid copper provides both a unique look and a superior grip for easy installation and removal by hand.

FAQ
Will this thread protector come loose when shooting?
When properly hand-tightened, the thread protector should remain secure during firing. The knurling provides excellent grip for applying sufficient torque. We recommend checking it periodically, as with any threaded component.
Is this compatible with my Gen 5 Glock 19?
Yes, if your factory or aftermarket Glock 19 barrel is threaded in the standard 1/2×28 pattern (common for 9mm), this copper thread protector will fit perfectly. Always verify your barrel’s thread pitch before ordering.
