Trijicon HD Night Sight Yellow Glock 20, 21, 29, 30, 41 GL104Y

Large-frame Glock pistols in serious calibers deserve serious sights - and the Trijicon HD Night Sights GL104Y brings the HD front sight acquisition advantage specifically to the large-frame Glock family with a yellow photoluminescent front outline that creates warm, high-contrast front sight visibility in any lighting condition from bright daylight to complete darkness.

The GL104Y fits Glock models 20, 21, 21SF, 29, 30, 36, and 41, including S and SF variants — covering the complete range of large-frame Glock configurations across 10mm, 45 ACP, and other chamberings. The Glock 20 Night Sight Set GL104Y is purpose-built for these specific large-frame models, ensuring proper dovetail installation and HD sight alignment on compatible platforms. Professional installation is recommended.

The Yellow Night Sights GL104Y yellow photoluminescent paint ring around the taller front sight tritium lamp creates a warm, high-contrast visual reference that draws the eye immediately and naturally to the front sight under stress - faster and more reliably than standard three-dot configurations in transitional lighting and dynamic defensive situations. The taller HD front blade provides greater visual presence above the rear sight, accelerating front-sight acquisition without the deliberate search for the aiming point when speed matters most.

Three-dot green tritium illumination provides self-luminous performance in complete darkness, without batteries or any electronics.

The Trijicon night sights GL104Y black rear sight features a wider U-shaped notch that keeps the HD front sight clearly framed and visible in poor lighting conditions. The steeply hooked front surface of the rear sight enables emergency one-handed slide operation - a practical tactical detail that matters in demanding defensive and hunting applications where large-frame Glocks are commonly deployed.
