Trijicon HD XR Night Sight Set FN 509 Green Tritium Orange Outline Front

The Trijicon HD XR Night Sight Set is a premium tritium-powered aiming upgrade engineered specifically for the FN 509 pistol. Sold as a complete front and rear set, the HD XR is built for duty, concealed carry, and home-defense use, delivering a high-visibility sight picture in any lighting condition.

The front sight features a green tritium lamp encircled by a high-contrast orange outline ring, paired with Trijicon's signature domed sapphire cap that focuses the tritium illumination for a 2X brighter aiming point. The rear sight is configured with a green tritium lamp and a black outline, producing a crisp three-dot picture day or night. The black sight frame provides a clean, low-glare finish that won't telegraph position during concealed carry.

Co-developed with input from law enforcement agencies, the HD XR platform offers an expanded field of view and a precise sight picture that excels at longer-range engagements while retaining the snag-free profile expected of a defensive handgun setup. Professional installation is recommended to ensure the set seats correctly on the FN 509 slide.
