The Hi-Viz GMPFD21 FASTDOT H3 Sight Set is a pistol night sight set designed for aiming reference on Smith & Wesson M&P pistols. This tritium and fiber optic system uses a red front and green rear configuration for visibility in varied lighting conditions.

It fits Smith & Wesson M&P compact, full-size, Shield, and Shield Plus models but does not fit optic-ready or EZ variants.
