FAQ
Will this fit my Glock 19 Gen 5 with a factory threaded barrel?
Yes. Factory Glock threaded barrels in 9mm and .357 SIG typically use the 1/2×28 thread pattern, making this protector a direct fit.
How do I install the thread protector?
Simply hand-tighten it onto your clean barrel threads until snug. The knurling provides ample grip. Do not use excessive force or tools, as this can damage the threads.
