FAQ
Will this fit my Glock 19 Gen 5 with a factory threaded barrel?
Yes. If your factory or aftermarket Glock barrel for 9mm or .357SIG has 1/2×28 threads, this protector is designed to fit it perfectly.
Why is it called “Naked” finish?
“Naked” means it has no final protective coating like nitride, bluing, or chrome. It is raw machined steel, which can develop a patina or light surface rust if not kept oiled, but can also be easily painted or coated at home.
