Trijicon HD Night Sight Yellow Glock GL101Y

The Trijicon HD Night Sights GL101Y gives standard-frame Glock owners the HD front-sight acquisition advantage with a yellow photoluminescent outline that creates warm, high-contrast front-sight visibility in any lighting condition. The HD configuration is built specifically for tactical shooters who need faster, more natural front-sight acquisition than standard three-dot designs can provide.

The GL101Y fits Glock models 17, 17L, 19, 22, 23, 24, 25, 26, 27, 28, 31, 32, 33, 34, 35, 37, 38, and 39 - covering the most widely carried standard and compact Glock configurations for defensive and duty use.

The Glock 17 19 Night Sights GL101Y yellow photoluminescent ring around the front sight tritium lamp creates an immediately dominant visual reference that draws the eye to the front sight naturally under stress. The taller front blade gives the HD front sight greater visual presence above the rear sight, accelerating front-sight acquisition in transitional lighting and dynamic defensive situations without any conscious search for the aiming point. Three-dot green tritium illumination handles complete darkness without batteries or electronics.

The Trijicon Glock sights GL101Y black rear sight runs a wider U-shaped notch that keeps the HD front sight clearly framed and visible in poor lighting. The hooked front surface of the rear sight assists emergency one-handed slide operation - a practical tactical feature for dynamic defensive use.

Professional installation is recommended for the Pistol sights GL101Y.
