Trijicon Bright & Tough Night Sights for FN 509 – 3-Dot Tritium

The Trijicon Bright & Tough Night Sights for the FN 509 deliver self-luminous tritium visibility in complete darkness without batteries or external light sources. These fixed sights feature a classic 3-dot configuration with green tritium lamps, providing instant target acquisition in low-light conditions. Designed specifically for defensive and duty use, they maintain zero regardless of lighting conditions.

Machined from steel with a matte black finish, these sights mount directly to the FN 509's dovetail cuts. The tritium lamps are encapsulated in sapphire jewels for maximum brightness and protection, maintaining visibility for over 12 years. White painted rings surround each tritium insert for enhanced daylight visibility. Installation requires a sight pusher tool or professional fitting.
