Trijicon HD Night Sight Set; Orange - for FN 509 FN104-C-600992

The FN 509 is a proven duty and defensive pistol built to the standards that FN's military and law enforcement heritage demands - and the Trijicon HD Night Sights FN104-C-600992 gives FN 509 owners the HD front sight acquisition advantage with an orange photoluminescent front outline that creates immediate, high-contrast front sight visibility in any lighting condition from bright daylight to complete darkness.

The FN104-C-600992 is designed specifically for the FN 509 sight configuration - a purpose-built fit that installs correctly and delivers proper HD sight alignment on this specific platform. Every Trijicon HD Night Sights set is engineered to the exact dimensions of the handgun it was made for, ensuring correct installation and reliable performance from the start. Green tritium lamps are warranted for 12 years from the date of manufacture. Professional installation is recommended.

The Orange Front Night Sights FN104-C-600992 orange photoluminescent paint ring around the taller front sight tritium lamp creates a warm, high-contrast visual reference that draws the eye immediately and naturally to the front sight under stress - faster and more reliably than standard three-dot configurations in transitional lighting and dynamic defensive situations. The taller HD blade gives more visual presence above the rear sight, accelerating front-sight acquisition without any conscious search for the aiming point when the situation demands a fast sight picture. Three-dot green tritium provides self-luminous performance in complete darkness without batteries.

The Trijicon night sights FN104-C-600992 black rear sight features a wider U-shaped notch that keeps the HD front sight clearly framed and visible in poor lighting conditions. The steeply hooked front surface of the rear sight enables emergency one-handed slide operation for dynamic defensive use.
