This Thread Protector 1/2 x 28 is a fundamental Glock part for anyone running a threaded 9mm or .357SIG barrel. Its job is simple: it screws onto your barrel’s threads to protect them from impact, dirt, and debris when a muzzle device isn’t installed. The knurled thick spiral design provides a supremely positive grip for hand-tightening, even with wet or gloved hands. This ensures your barrel’s critical threads remain in perfect condition for when you attach your compensator or suppressor.
Key Features
- Precision machined with 1/2×28 threads to match common 9mm and .357SIG barrel threading.
- Aggressive knurled thick spiral pattern for maximum grip and easy installation/removal.
- Finished in “Naked” stainless steel for a clean, durable look that resists corrosion.
- Compact design adds minimal length and weight to your pistol’s barrel.
- Serves as a basic thread protector and can also provide a sleek, finished look to your setup.
Built For

FAQ
Will this fit my factory Glock barrel?
No, factory Glock barrels are not threaded. This thread protector is specifically for aftermarket barrels that have been manufactured with 1/2×28 threads.
Is this compatible with .40 S&W barrels?
Typically, no. While .40 S&W can sometimes use 1/2×28 threads, it is less common and we recommend verifying your specific barrel’s thread pitch. This protector is confirmed for 9mm and .357SIG applications.
