Frequently Asked Questions
Will these sights fit my S&W M&P 380 Shield EZ without modification?
Yes. The HiViz EZN321 is engineered specifically for the Smith & Wesson M&P 380 Shield EZ and is designed to be a direct drop-in replacement for the factory sights. Standard sight pusher tools are recommended for rear sight installation. No milling or gunsmithing is required for most users.
How do tritium and fiber optic work together in the LightWave H3 system?
HiViz's LightWave H3 technology combines a self-illuminating tritium capsule with a fiber optic light pipe in a single sight element. In bright conditions, the fiber optic channels ambient light for an ultra-bright, vivid aiming point. In low-light or darkness, the tritium element glows continuously without any batteries or charging required — giving you a reliable sight picture 24/7.
How long will the tritium element remain effective?
Tritium is a low-level radioactive gas that glows through a process called radioluminescence. The tritium vials used in night sights like the HiViz LightWave H3 have an approximate half-life of 12 years, meaning the sights will remain usefully bright for self-defense and carry purposes for 10–12 years under normal conditions before brightness noticeably diminishes.
