The HiViz LiteWave H3 Sight Set (brand part no. MPN421) combines a green tritium front sight with an orange fiber optic rear sight, built at factory height for the Smith & Wesson M&P. HiViz pairs tritium with its Litepipe technology so the set delivers true 24-hour illumination, glowing at night while staying visible under daylight from the orange fiber optic rear. All-steel construction keeps the set rugged and durable enough for personal defense, law enforcement, or military use. This set does not fit the CORE, M&P 22, or M&P Long Slide models.
