Trijicon HD Night Sight Set Green Tritium Fiber Optic Front / Green Tritium Rear - Glock MOS 17/19/34

The Trijicon HD Night Sight Set is a three-dot, self-illuminating tritium sight set purpose-built for Glock MOS (Modular Optic System) standard-frame pistols. Sized specifically for the 17MOS, 19MOS, and 34MOS slides, this HD (Heavy Duty) configuration pairs a tall, high-visibility front blade with a two-dot green tritium rear for fast, intuitive sight acquisition in any lighting condition.

The front sight features a taller blade with an aiming point ringed in orange for quick daytime indexing, paired with a self-illuminating green tritium lamp for a bright aiming reference in low light. The rear sight uses a standard two-dot green tritium configuration. Tritium-phosphor lamps are housed in a rugged metal body with a silicone rubber cushion to protect against recoil and rough handling.

Because the tritium is self-powered, the HD Night Sights require no batteries and no switches; they are always on, ready to go. Trijicon's proprietary HD sight geometry makes the front dot faster to pick up at the draw while the rear notch keeps the dots aligned under stress. Whether used as a primary sighting system or as a co-witnessed backup to a slide-mounted optic, the HD Night Sights deliver a hard-use aiming solution for the duty, defensive, or carry Glock.

This listing is for the front and rear sight set, with the rear sight dimensioned specifically for Glock MOS standard-frame slides.
