Drop-in threaded 9mm barrel for Glock 43 and Glock 43X pistols. Replaces the factory barrel without fitting or gunsmith work. 1/2x28 muzzle threading lets you mount a compensator, suppressor, or thread protector — protector included with the barrel.
Built from 416R stainless steel and finished in hard-coat black nitride for corrosion resistance and a slick, low-friction surface. The nitride process runs the full length of the barrel and through the chamber, so wear from holster draw and brass extraction stays minimal over a long round count.
Lube the slide rails and barrel hood before the first range trip. Tolerances can run tight on a fresh barrel; a few cycles by hand and the first 50 to 100 rounds will seat the fit. Verify your suppressor or compensator is rated for 1/2x28 9mm before mounting.
