Hiviz Rgmfd21 Fastdot H3 Red/Fiber Optic Green Tritium Frame Ruger Max-9
The Hi-Viz FastDot H3 is a tritium and fiber-optic sight set purpose-built for the Ruger Max-9, delivering fast target acquisition in any light condition without batteries or electronic dependency. This single-dot sight system pairs fiber-optic brightness in daylight with encapsulated tritium for reliable low-light and night shooting, making it equally at home at the range, in defensive training, or in the field. If you carry a Max-9 for personal protection or duty, a sight that works around the clock—without fidgeting with batteries or complex adjustments—simplifies your life and sharpens your shot.
Hi-Viz engineered the FastDot H3 with a low-profile design that clears standard holsters without modification, so you're not forced to choose between good sights and gear compatibility. The LiteWave H3 platform combines the speed of a single bright dot with the durability of fully encapsulated tritium, eliminating the fragility and light leakage of traditional vial sights. You get the same rapid sight picture in bright sun and pitch-black conditions—no toggling, no learning curve.
Hi-Viz backs the tritium with a 12-year warranty, giving you confidence in long-term reliability. Whether you're training for defensive proficiency or simply want sights that work when you need them, the FastDot H3 removes variables from your shooting equation.
