HiViz CKMFD21 FastDot H3 Tritium Night Sight - Taurus G3/G3C/GX4

The HiViz CKMFD21 FastDot H3 delivers tritium-powered visibility for Taurus G3, G3 Tactical, G3C, GX4, and GX4 XL pistols. This self-illuminating sight system provides consistent target acquisition in complete darkness without batteries or external light sources.

What Makes This Different

Unlike standard three-dot systems, the FastDot H3 uses a single tritium front sight paired with a blacked-out rear for faster target acquisition. The simplified sight picture eliminates dot confusion under stress while maintaining precision accuracy. Tritium inserts provide 12-year guaranteed illumination that won't fade during critical moments.
