The HiViz MPSN621 LiteWave H3 sight set transforms target acquisition on Smith & Wesson Shield pistols through advanced tritium and fiber optic technology. This hybrid sight system delivers reliable aiming capability in all lighting conditions, from bright daylight to complete darkness.
What Makes This Different
The LiteWave H3 technology combines self-illuminating tritium inserts with bright fiber optic light pipes in a single sight system. Standard iron sights offer limited visibility in low light, while basic night sights lack daytime brightness. This hybrid design captures ambient light through fiber optics during the day and relies on tritium illumination when darkness falls, providing consistent sight picture regardless of conditions.
Key Features
- Green tritium front sight with orange outline for 24/7 visibility
- Orange fiber optic rear sight maximizes light gathering
- Direct replacement for factory S&W Shield sights
- Tool-free LitePipe replacement system
- Machined steel construction with protective sight guards
- Low-profile design maintains holster compatibility
- 12-year tritium half-life rating
The sight set performs across multiple shooting disciplines, from concealed carry to competitive shooting. The bright orange fiber optic rear sight creates clear contrast against the green tritium front post, enabling faster target transitions and improved accuracy. Weather-resistant construction withstands moisture, temperature extremes, and recoil stress without losing zero or brightness.
