This Thread Protector 1/2 x 28 in Rose Gold is a functional and aesthetic upgrade for your Glock or compatible pistol barrel. If you run a 9mm or .357SIG barrel with standard 1/2×28 threads, this protector keeps those threads clean from debris, impact, and corrosion when a muzzle device isn’t installed. The straight-fluted rose gold finish offers a distinct, modern look that sets your build apart while performing an essential protective role. It’s a simple yet critical Glock part for maintaining your barrel’s integrity.

FAQ
Will this fit my Glock 19 barrel?
Yes, it will fit any aftermarket or OEM Glock barrel chambered in 9mm or .357SIG that has been threaded to the common 1/2×28 specification. Always verify your barrel’s thread pattern before purchase.
Is the rose gold finish durable?
Absolutely. The PVD (Physical Vapor Deposition) coating is far more durable than standard plating or paint. It provides excellent resistance to holster wear, corrosion, and fading, ensuring your Glock parts retain their look.
