TruGlo’s TFO sight set (part no. TG231S2) pairs the brand’s fiber-optic technology with tritium night sights, so the sight picture stays bright whether you’re shooting in daylight or complete darkness.

\n

The set uses a 3-dot, tritium square-front and square-notch rear pattern in green, is CNC-machined from steel, and conceals the fiber so it cannot be seen from the target’s side. No batteries are required, and the design is snag-resistant and fits standard holsters.
