FAQ

Will this fit my Glock 19 Gen 5 MOS with a threaded barrel?
Yes, if your factory or aftermarket Glock barrel is chambered in 9mm or .357SIG and has the standard 1/2×28 thread pitch, this thread protector will fit perfectly.

Does it require a wrench or any tools to install?
No, it is designed to be hand-tightened. The straight fluting gives you plenty of grip to secure it firmly by hand. Avoid over-tightening with tools, as this can damage the aluminum.
