The Glock G43X MOS with threaded barrel (brand part no. UX4350201FRMOSTB) is a 9mm slimline pistol configured for suppressor and compensator use, pairing the 43X’s compact grip with a 3.41-inch factory threaded barrel. Glock cuts the black steel slide for optics and serrates it for positive manipulations, while the black polymer frame carries an accessory rail and ambidextrous controls. Capacity is 10+1, and Glock’s firing pin and trigger safeties keep the striker-fired action drop-safe. Among semi-auto handguns, this threaded 43X MOS favors shooters who want a slim host for a suppressor or compensator with red-dot capability built in.
