The TruGlo TG131XTY TFO sight set combines tritium and fiber optic technology to deliver consistent target acquisition in any lighting condition. This Springfield Armory XD-specific sight system features a green tritium/fiber optic front sight paired with a yellow tritium/fiber optic rear sight for enhanced contrast and faster sight alignment.
What Makes This Different
TruGlo's patented TFO (Tritium Fiber Optic) technology merges the brightness of fiber optics with the reliability of tritium gas tubes. While standard tritium sights fade in bright light and fiber optic sights disappear in darkness, TFO sights maintain visibility across the full spectrum of lighting conditions. The contrasting green front and yellow rear sight configuration creates an intuitive sight picture that reduces target acquisition time by up to 30% compared to traditional three-dot systems.Key Features
