FAQ
Will this fit my Glock 19 Gen 5 with a factory threaded barrel?
Yes, if your factory or aftermarket Glock barrel for 9mm/.357SIG is threaded 1/2″x28, this thread protector will fit correctly. Always verify your barrel’s thread pitch before ordering.
Does the gold finish wear off easily?
The finish is a durable plating or PVD coating designed for handling and use. Like any finish, it can wear over time with heavy holstering or abrasive contact, but it provides excellent corrosion resistance and retains its look under normal range conditions.
