Faxon Firearms EXOS-543 Compensator for Glock Gen 4, 9mm, 1/2×28

The Faxon Firearms EXOS-543 Compensator (brand part no. FF-P-A-COMP-DS-G-02) is designed for Glock Gen 4 9mm pistols, with fit and function testing performed specifically on the Glock 19, Glock 17, and Glock 34, all Gen 4. Fitment on other pistols or generations isn’t guaranteed. Machined from 6061 aluminum with a black anodized finish and threaded 1/2×28 at roughly 1.10 inches overall, it uses Faxon’s uniquely angled front-port, single-chamber design to deflect gas upward instead of only sideways, reducing muzzle climb and recoil while improving reliability. Barrel protrusion is optimized for Faxon-branded barrels for a flush fit; with other barrels, protrusion should be .600 inches or less. Each compensator ships complete with thread locker, two 6-32 set screws, and a 1/16-inch Allen wrench.
