TruGlo TG131G3 Fiber-Optic Glock 42/43/43X/48 Pistol Sight Set - Red Front / Green Rear - Black Nitride Fortress

The TruGlo TG131G3 Brite-Site fiber-optic pistol sight set is purpose-built for the slimline Glock 42 / 43 / 43X / 48 pistols (excluding MOS variants). TruGlo's fiber-optic technology channels available ambient light into bright, easy-to-acquire aiming points, delivering fast target acquisition in daylight and low-light conditions alike.

The set pairs a red fiber-optic front sight with a green fiber-optic rear in a square-notch configuration for instant visual contrast against virtually any background. The sight bodies are CNC-machined from steel and finished in TruGlo's signature Black Nitride Fortress coating for excellent corrosion and wear resistance. A snag-resistant, low-profile design keeps the sights tucked in close and lets the pistol draw cleanly from standard holsters.

Installation drops into the factory dovetail cuts on the slimline Glock platform, and the low sight profile co-witnesses cleanly with factory-height sights. Whether you are running a concealed-carry Glock 43 or a full-size Glock 43X / 48, this sight set delivers a meaningful aiming-point upgrade. TruGlo recommends professional installation to ensure proper zero and seating in the dovetail. This listing is for a brand new sight set.
