Factory-style 9mm thread protector for any 1/2x28 threaded Glock aftermarket or OEM barrel. Compatible with threaded 9mm barrels on Glock 17, Glock 19, Glock 26, Glock 34, Glock 43, and Glock 48 pistols - if your barrel runs 1/2x28 muzzle threads, this protector will seat. Finished in gold titanium nitride (TiN), a hard ceramic PVD coating that resists heat, corrosion, and carbon fouling while adding a contrasting accent to a black or stainless barrel. The knurled outer ring gives a positive grip for hand-tight install and removal - no wrench required. Thread pitch: 1/2x28 (standard 9mm) TiN PVD finish over stainless core Knurled grip for tool-free install Seals muzzle threads against debris and fouling Fits any 1/2x28 Glock-pattern 9mm barrel Hand-tight is enough - do not over-torque. Verify your barrel's thread pitch before ordering; 1/2x28 is standard on 9mm Glock threaded barrels, but conversion barrels in other calibers use different pitches.
