The Hi-Viz LiteWave H3 Tritium/Litepipe Night Sights MPSN421 is a handgun night sights set designed for low-light and daytime sight alignment.

This sight set integrates tritium illumination with LitePipe fiber elements to maintain visibility across lighting conditions. It features a green tritium front sight with a white ring and an orange rear sight for contrast differentiation. The design fits Smith & Wesson M&P Shield pistols chambered in 9mm, .40 S&W, and .45 calibers with factory sight height compatibility. The unit installs into standard slide dovetail cuts and uses a fixed front and rear configuration. This model fits Shield platforms and is used for replacing factory iron sights where improved visibility is required. In normal operation, the system provides continuous illumination through tritium and ambient light capture through fiber elements, supported by a 12 year tritium warranty for consistent handgun sight use.
