FAQ

Will this fit my Glock 19 threaded barrel?
Yes, if your Glock 19 barrel is threaded 1/2″ x 28, which is the standard for 9mm, this violet coil thread protector will fit perfectly.

Does the coil design really keep it from coming loose?
Absolutely. The spring tension of the coil applies constant pressure against the barrel threads, creating a secure grip that resists backing off under vibration, which is a common issue with simple screw-on protectors.
