Trijicon Bright & Tough Night Sights FN509 3-Dot Green Tritium White Outline

The Trijicon Bright & Tough Night Sights are a self-luminous 3-Dot iron sight set purpose-built for the FN509 pistol. Tritium phosphor-filled glass lamps in both the front and rear blades deliver a battery-free glow that produces a visible aiming point in low-light and no-light conditions, increasing night-fire accuracy as much as five times over standard iron sights. The front sight carries a highly visible photoluminescent white outline that speeds acquisition in daylight and at the draw.

Built around a rugged steel housing with a black finish, this front/rear set is designed for direct installation on the FN509. Both blades carry green tritium lamps framed by a white outline, presenting a clean and consistent 3-Dot aiming picture regardless of lighting. There are no batteries, switches, or electronics to manage - the lamps glow year after year and require nothing more than keeping the glass clean.
