This nickel-plated locking block fits the Glock 42, 43, 43X and 48 slimline pistols. It replaces the factory locking block in your slimline frame and adds a bright nickel accent that shows against a black or colored frame.
Fit: Slimline Glock models only — Glock 42, 43, 43X and 48. It does not fit standard-frame pistols such as the Glock 17, 19, 22 or 23. For those, see our standard-frame locking block for the Glock 17, 22, 24, 31, 34 and 35 Gen 3.
Finish: Nickel plating over 17-4 stainless steel resists corrosion and wear from daily carry, sweat and cleaning solvents over years of use, which matters on a slimline pistol that often lives in an inside-the-waistband holster.
Features:
Confirm your model before ordering and function-check the pistol after installation.
