Trijicon HD XR Night Sights FN 509 Green Tritium Yellow Outline

The Trijicon HD XR Night Sight Set delivers superior target acquisition in all lighting conditions for FN 509 pistols. This sight system combines self-luminous tritium with high-visibility colored outlines to create faster sight alignment than standard three-dot configurations.

What Makes This Different

The HD XR design features a larger front sight aperture and thinner rear sight notch compared to traditional night sights. Green tritium lamps provide consistent illumination for 12+ years without batteries or external light sources. The yellow front sight outline creates maximum contrast against dark backgrounds, while the blacked-out rear sight eliminates distracting dots that can slow target acquisition.

Key Features

• Green tritium front and rear lamps rated for 12+ year lifespan
• Yellow front sight outline for enhanced visibility in daylight
• Machined steel construction with protective white outline
• Fits FN 509, 509 Compact, 509 Midsize, and 509 Tactical models
• Taller front sight height optimized for suppressor use
• Snag-resistant rear sight design with forward angle
• Professional installation recommended for proper zero

Field testing demonstrates improved first-shot accuracy in low-light scenarios compared to standard factory sights. The HD XR configuration excels in defensive shooting applications where rapid sight acquisition determines engagement success. Law enforcement agencies report faster qualification times and improved accuracy scores after switching to this sight system. The robust steel construction withstands repeated holster draw cycles and environmental exposure.
