The Faxon Firearms EXOS-523 Compensator for the Glock 43 in black anodized aluminum (brand part no. FF-P-A-COMP-SS-G-01) uses a uniquely angled front-port, single-chamber design to reduce muzzle climb and recoil on 9mm carry pistols. Constructed from 6061 aluminum, it threads on at 1/2×28 and is optimized to fit flush against a Faxon-branded barrel, though it also works with other threaded barrels as long as protrusion stays at .600 inches or less. The angled ports deflect gas upward instead of only to the sides, which cuts down on up-and-down muzzle movement and improves reliability compared to a straight-port design. Each compensator ships complete with thread locker, two 6-32 set screws, and a 1/16-inch Allen wrench for installation.
