The Trijicon HD Night Sights deliver superior target acquisition in all lighting conditions for Glock 20 and 21 large frame pistols. These professional-grade sights combine tritium illumination with high-visibility outlines to provide consistent sight picture from bright daylight through complete darkness.
What Makes This Different
Unlike standard three-dot configurations that can create confusion under stress, the HD design features a single green tritium front sight with bright yellow outline paired with a blacked-out rear sight. This contrast-focused system draws the eye naturally to the front sight for faster target engagement. The tritium elements maintain consistent brightness for 12+ years without batteries or external power sources.Key Features
