FAQ
Will this thread protector work on my Glock 19?
Yes, if your Glock 19 has a threaded barrel with a 1/2 x 28 thread pitch, this protector is compatible. Always verify your barrel’s thread specification before ordering.
Does the copper finish require special maintenance?
Copper will naturally develop a patina over time. This does not affect function. If you wish to maintain the shine, you can polish it with a soft cloth; the patina can also be removed with common copper cleaners.
