TruGlo Tritium X Glock 42/43/43X/48 Night Sight Set - White Outline Front / Green Tritium Rear

Upgrade your Glock's low-light aiming with the TruGlo Tritium X night sight set, purpose-built for Glock 42, 43, 43X, and 48 pistols (excludes MOS models). This front-and-rear sight pair combines a white outline tritium front post with a green tritium rear for fast, intuitive sight acquisition in dim or no-light conditions, with no batteries or switches to manage.

The sights are built on a rugged CNC-machined steel frame finished in TruGlo's signature Black Nitride Fortress coating for excellent wear and corrosion resistance. Self-illuminating Swiss tritium lamps provide a bright, consistent glow on both the front and rear elements, while the white outline ring around the front tritium vial draws the eye for quicker alignment under stress.

Installation is drop-in: the front post replaces the factory blade, and the rear sight slides into the factory dovetail. No permanent modification or gunsmithing required. Whether you carry a Glock 43 as your everyday concealed-carry pistol or rely on a 43X or 48 for home defense, the Tritium X set delivers reliable, snag-free aiming day or night.
