HiViz FastDot H3 Features The HiViz FastDot H3 pairs a bright Red fiber-optic front sight with a Green tritium rear creating a single-dot sight picture that is fast to find and easy to track under recoil. Fiber optic collects ambient light during the day for a vivid daylight sight picture while fully encapsulated tritium takes over in low light and darkness giving the sight true 24-hour usability. This dual illumination approach means the shooter never has to think about switching or relying on an external light source to see the sights. The steel sight bodies resist wear and impact far better than polymer alternatives holding zero through hard use. Because the tritium is fully encapsulated rather than exposed the glow stays protected from scratching and impact damage that would otherwise dim or crack a lamp extending the sight s useful service life considerably. Built specifically for the Sig Sauer Hellcat and Hellcat Pro the FastDot H3 drops in without requiring frame modification or a gunsmith fitting. The low-profile design was engineered to fit standard holsters so carriers will not need to buy a new holster to accommodate the sight picture. HiViz backs the tritium vials with a 12-year warranty reflecting confidence in the sight s long service life and giving owners a long runway before replacement is ever a concern. The contrasting Red and Green color scheme also reduces the chance of misreading the sight picture during a high-stress defensive encounter since the front and rear elements are never confused for one another. For concealed carriers who want a fast reliable sight picture day or night the HiViz FastDot H3 is a proven upgrade for the Hellcat platform that pays off every time the gun is drawn.
