The HIVIZ MPFD21 FastDot H3 Sight Set for S&W M&P delivers a low profile, all-steel front/rear sighting system that combines fiber optic illumination with ultra bright encapsulated tritium for 24 hour visibility. The red front sight paired with the green rear sight provides quick, intuitive target acquisition across all lighting conditions, while its compact design fits standard holsters and remains compatible with S&W M&P Shield, Shield Plus, and full-size and compact configurations (note: not for optic-ready models like 9EZ EZ 30 Super Carry or EZ 380). Patented FastDot technology ensures a precise, single-dot sight picture that remains reliable in any light, and the rugged construction stands up to daily carry and demanding use. HIVIZs Tritium illumination is supported by a 12-year warranty against tritium failures due to workmanship or material defects, subject to proper use and inspection. This sight set is ideal for house, field, or range applications where fast target acquisition and reliable low-profile performance are essential, providing a consistent reference point for rapid shooting while maintaining compatibility with standard holsters and everyday carry setups.
