Trijicon HD Night Sights for Glock 21 – Orange Outline Front

The Trijicon HD Night Sights deliver a large, high-visibility sight picture optimized for fast target acquisition in defensive shooting scenarios. The front sight features a bright orange outline surrounding a tritium lamp for 24-hour visibility, while the blacked-out rear sight eliminates distractions and draws your eye to the front post. Designed specifically for Glock 21 pistols, these three-dot tritium sights provide reliable aiming reference from full daylight through complete darkness.

Machined from steel with a matte black finish, the HD sights install in the factory dovetail cuts on your Glock 21 slide. The front sight's wider profile and contrasting orange ring accelerate sight alignment under stress. Tritium lamps are self-luminous and maintenance-free, requiring no batteries or external light source. Trijicon backs these sights with a 12-year tritium warranty.
