This Thread Protector 1/2 x 28 in Copper is a simple, essential accessory for any Glock owner with a threaded barrel chambered in 9mm or .357SIG.

The durable copper construction provides excellent corrosion resistance while adding a distinct, classic metallic accent to your firearm’s profile. Keeping your threads in perfect condition ensures reliable attachment for suppressors, compensators, or brakes when you need them.

FAQ
Will this thread protector fit my Glock 19 Gen 5 with a factory threaded barrel?
Yes. If your factory or aftermarket Glock barrel has 1/2″ x 28 threads, which is the standard for 9mm, this copper thread protector will fit perfectly.
Does the copper require any special maintenance?
Copper is naturally corrosion-resistant, but it will tarnish and develop a patina with handling and exposure. This is normal and does not affect function. You can polish it to maintain its shine if desired.
