Faxon EXOS-524 9mm pistol compensator for Smith & Wesson M&P Shield and Shield Plus 9mm pistols. Built from lightweight 6061 aluminum with a black anodized finish. Features a single-chamber front port angled to optimize gas deflection, resulting in reduced muzzle climb and improved shot-to-shot consistency. This compensator uses 1/2x28 threads and sits flush with the slide when paired with a Faxon barrel or other barrels with .600" or less protrusion. Includes thread locker, two set screws, and an Allen wrench for installation.
