Trijicon HD XR Night Sights Green Tritium Glock 17/19/45 MOS Set

The Trijicon HD XR Night Sight Set delivers enhanced target acquisition in all lighting conditions with self-illuminating tritium technology. This sight system combines a green tritium front sight with yellow outline and green tritium rear sight specifically engineered for Glock MOS pistols.

What Makes This Different

The HD XR design features a taller front sight profile that provides faster sight acquisition compared to standard factory sights. Tritium gas tubes maintain consistent illumination for 12+ years without batteries or external light sources. The yellow front sight outline creates maximum contrast against dark backgrounds while the rear sight eliminates distracting outlines for cleaner sight picture.

Key Features

• Green tritium front sight with high-visibility yellow outline ring
• Green tritium rear sight with U-notch configuration
• Machined steel construction with black Melonite finish
• Fits Glock 17 MOS, 19 MOS, and 45 MOS models
• 12+ year tritium lifespan with consistent brightness
• Snag-resistant rear sight edges for smooth draw
• Professional installation recommended for proper zero

Field testing demonstrates reliable performance across temperature extremes from -40°F to 160°F. The tritium elements maintain visibility in complete darkness while the contrasting outlines excel in daylight and low-light transitions. Law enforcement and competitive shooters report improved split times and target engagement speed compared to standard three-dot configurations.
