The Trijicon HD XR Night Sight Set for Smith & Wesson M&P CORE pistols (brand part no. 601172) refines the proven HD platform with a thinner front post that exposes more of the target at distance. Trijicon pairs green tritium lamps front and rear for a battery-free three-dot picture with an orange photoluminescent ring around the front lamp for fast pickup in fading light. The wide U-notch rear keeps the narrow front post quick to find under stress, and steel housings handle duty and holster wear. Among gun sights, this HD XR set favors M&P CORE shooters who want a finer aiming point for precise shots at extended range.
