This Thread Protector 1/2 x 28 is a simple, essential piece for maintaining your Glock barrel threads. Designed for 9mm and .357SIG barrels with the common 1/2×28 thread pitch, it screws directly onto your muzzle to protect the critical threading from impact, debris, and corrosion. It’s a must-have for any shooter who uses a threaded barrel but isn’t always running a muzzle device, ensuring your threads remain in perfect condition for when you attach a compensator or suppressor. The “Naked” finish means it’s raw, uncoated stainless steel, ready for use or a custom finish.

FAQ
Will this fit my factory Glock barrel?
No, factory Glock barrels are not threaded. This thread protector is designed for aftermarket threaded barrels specifically cut with a 1/2×28 thread pattern.
How do I keep it from loosening during fire?
For a secure fit, we recommend applying a small amount of vibratite or a similar low-strength thread locker to the threads before hand-tightening. This will prevent it from walking off under recoil while still allowing for easy removal.
