TruGlo TFO TG131MPT S&W M&P/SD9/SD40 Night Sight Set - Green Front / Yellow Rear - Black Nitride

Upgrade your Smith & Wesson M&P pistol with the TruGlo TFO TG131MPT handgun night sight set, the original Tritium + Fiber-Optic sighting system from TruGlo. Built for fast, intuitive target acquisition in any lighting condition, this set pairs a green tritium/fiber optic front sight with a yellow tritium/fiber optic rear for instant daylight visibility and a bright glow after dark.

The set fits Smith & Wesson M&P, SD9, and SD40 pistols and uses a square front blade paired with a U-notch rear for a clean, snag-resistant sight picture. TruGlo's patented TFO design concentrates ambient light through the fiber optic channel during the day and falls back on tritium vials for a self-illuminated sight picture at night, with no batteries required.

Construction is CNC-machined steel finished in Black Nitride Fortress for excellent wear and corrosion resistance, with a 0.060" fiber diameter and a 1.0" front sight length. Drop-in ready and a popular upgrade for concealed carry, duty, and home-defense M&P pistols, the TG131MPT pulls double duty as a daytime fiber optic sight and a true low-light/night sight.
