This Thread Protector 1/2 x 28 in a Knurled Naked finish is a straightforward, essential piece of gear for any Glock owner running a threaded barrel. It’s designed to protect the critical threads on your 9mm or .357SIG barrel from impact damage, debris, and corrosion. By simply screwing it on, you safeguard your investment and ensure your muzzle device, like a compensator or suppressor, mounts cleanly and correctly every time. This is a fundamental part for maintaining your firearm’s functionality and value.

FAQ
Will this fit my Glock 19 Gen 5 with a factory threaded barrel?
Yes. If your factory Glock barrel is threaded 1/2 x 28 for 9mm, this thread protector is designed to fit it perfectly.
Why is it left uncoated or “Naked”?
The Naked finish gives you a neutral, raw steel base. This allows you to leave it as-is for a utilitarian look, or it can be easily cerekoted or finished to match your specific slide or barrel color without the need for stripping.
How do I prevent it from loosening during fire?
For range use, hand-tightening is typically sufficient. For absolute security, especially during sustained fire, a small amount of high-temperature thread locker (like Rocksett) on the threads can be used, but this may require heat to remove later.
