Trijicon HD XR Night Sight Set Green Tritium Yellow Outline Front / Green Tritium Rear - Fits Glock 17 MOS / 19 MOS / 34 MOS / 45 MOS

The Trijicon HD XR Night Sight Set is a self-illuminating tritium night sight pair purpose-built for Glock MOS-pattern pistols. Each lamp is filled with tritium gas that charges from ambient light and emits a continuous green glow in low light and total darkness, with no batteries, switches, or activation needed.

The front sight uses Trijicon's slimmer HD XR post profile, with a green Tritium lamp ringed by a yellow photoluminescent paint outline that creates a high-contrast halo around the green dot for fast target acquisition. The rear sight pairs a green Tritium lamp in a wide U-notch, and its profile is specifically contoured to clear the optics-mounting plate on Glock MOS slides so a slide-mounted red dot co-witnesses cleanly.

This set is fitment-cut for Glock MOS-pattern pistols including the 17 MOS, 19 MOS, 34 MOS, and 45 MOS. The sights press into factory dovetails with no gunsmithing required and are built on a snag-resistant black sight frame. Tritium lamps are warranted for 12 years from the date of manufacture.
