FAQ

Will this fit my Glock 19 Gen 5 threaded barrel?
Yes, if your factory or aftermarket Glock 19 barrel is threaded 1/2×28 for 9mm, this thread protector will fit perfectly. Always verify your barrel’s thread pitch before ordering.

Is the violet color durable?
Absolutely. The color is not a paint but a hard-coat anodization, meaning it’s electrically bonded to the aluminum for excellent resistance to wear, chipping, and fading under normal use.
