Trijicon HD Night Sights Green Tritium Yellow Outline Front - Glock 17/17L/19 Standard Frame

The Trijicon HD Night Sights (GL101Y) are a self-luminous three-dot tritium night sight set built specifically for Glock Standard Frame pistols. The front sight uses a taller blade housing a green tritium lamp ringed in yellow photoluminescent paint, giving the shooter a vivid, high-contrast aiming point in daylight and instant visibility in total darkness. The rear sight pairs a matching green tritium lamp with a subdued black outline, so the eye is naturally drawn to the front blade for faster, more intuitive front-sight focus.

Constructed on a rugged steel frame finished in black, these sights are engineered to handle the recoil and holster wear of daily-carry and duty Glock pistols. Because each tritium lamp is self-powered, the sights require no batteries or switches and remain usable in any lighting condition. The three-dot pattern produces a clean, repeatable sight picture, and the taller front blade combined with the yellow photoluminescent outline dramatically speeds up both daylight target acquisition and low-light indexing compared to factory iron sights.

This set is designed for Glock Standard Frame pistols, including the Glock 17, 17L, and 19. Installation drops into the factory dovetail cut with no permanent slide modification, making the HD Night Sights a direct, no-gunsmithing upgrade for duty, home-defense, and everyday-carry pistols.
