HiViz MPSN421 LiteWave H3 Sight Set S&W Shield Green Tritium

The HiViz MPSN421 LiteWave H3 sight set transforms target acquisition on the Smith & Wesson Shield with dual-illumination technology that performs in any lighting condition. This hybrid sight system combines green tritium night illumination with fiber optic daylight gathering for consistent sight picture from dawn to dusk.

What Makes This Different

Unlike standard three-dot sights or single-illumination systems, the LiteWave H3 delivers both tritium and fiber optic illumination in a single sight set. The front sight features green tritium with white outline for night visibility, while the orange fiber optic rear sight maximizes contrast during daylight hours. This dual-technology approach eliminates the visibility gaps common with conventional sight systems.

Key Features

• Green tritium front sight with white outline for low-light visibility
• Orange fiber optic rear sight for enhanced daylight contrast
• Direct replacement for factory S&W Shield sights
• Steel construction with protective sight housings
• Self-illuminating tritium rated for 12+ years of visibility
• Fiber optic elements gather ambient light automatically
• Standard height profile maintains holster compatibility

Range performance shows faster target acquisition compared to standard black sights, particularly during low-light conditions or indoor shooting scenarios. The contrasting orange rear sight creates clear sight alignment against various target backgrounds, while the tritium front sight remains visible in complete darkness. Competition shooters report improved split times, while concealed carriers benefit from the enhanced visibility during defensive scenarios.
