FAQ

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

Do I need to use a wrench or thread locker to install it?
No. It is designed to be hand-tightened securely. Using a wrench risks over-tightening and damaging the threads. Thread locker is generally not recommended for this application.
