Trijicon HD XR Night Sights Green Tritium FN FNP/FNX 600891

The Trijicon HD XR Night Sight Set transforms low-light shooting accuracy with self-luminous tritium inserts that require no batteries or external light sources. This sight set delivers consistent sight picture acquisition in complete darkness for 12+ years through tritium's natural radioactive decay process.

What Makes This Different

The HD XR design features a taller front sight profile compared to standard factory sights, creating faster target acquisition and improved sight radius. The orange outline front sight provides high contrast against varied backgrounds during daylight hours, while the tritium lamp maintains visibility in darkness. This dual-illumination system eliminates the brightness adjustment requirements found in electronic sight systems.

Key Features

• Self-luminous green tritium lamps with 12-year minimum brightness guaranteeOrange outline front sight for enhanced daylight visibility and contrastMachined steel construction with protective nitride finish
• Snag-resistant rear sight design with angled edges
• Factory-engineered fit for FN FNP and FNX pistol models
• No batteries, switches, or external charging required
• Three-dot sight configuration for consistent sight alignment

Field performance remains consistent across temperature ranges from -40°F to 160°F without brightness degradation or zero shift. The steel construction withstands repeated slide cycling and holster draw cycles without loosening or damage. Law enforcement agencies report maintained zero accuracy through thousands of training rounds and duty carry cycles.
