The Faxon Match Series fluted 9mm barrel (brand part no. GB910N43SGQ-T) is a drop-in upgrade for the Glock 43 and 43X. Machined in-house from 416-R stainless steel and given a black Nitride/PVD finish, it pairs a fluted profile with match-grade tolerances for a tighter lockup than the factory barrel. Conventional rifling keeps it compatible with a wide range of ammunition, including cast lead, and a 1:10-inch twist stabilizes standard 9mm bullet weights. The threaded muzzle lets shooters run a compensator on their carry-size Glock without any gunsmithing.
