HiViz SG320FD21 FastDot Sight Set SIG P320 Red Fiber Optic Green Tritium

The HiViz SG320FD21 FastDot H3 sight set transforms SIG P320 pistols with a high-contrast red fiber optic front sight paired with green tritium rear sights. This combination delivers rapid target acquisition in all lighting conditions while maintaining the precision shooters demand from their carry and duty pistols.

What Makes This Different

Unlike standard three-dot configurations that can create sight picture confusion, the FastDot system uses contrasting colors to eliminate alignment errors. The red fiber optic front sight draws the eye instantly in daylight conditions, while the green tritium rear provides a clear reference point that won't compete with the front sight. This asymmetrical approach reduces sight acquisition time by up to 30% compared to traditional white dot systems.

Key Features

• Red LitePipe fiber optic front sight with protective steel ring for maximum light gathering
• Green tritium rear sight with white outline for 24-hour visibility
• Drop-in replacement for factory SIG P320 sights - no gunsmithing required
• Steel construction with corrosion-resistant finish rated for 50,000+ rounds
• Low-profile design maintains holster compatibility with most IWB and OWB holsters

Range testing demonstrates consistent 2-inch groups at 25 yards with the enhanced sight picture improving split times in rapid-fire drills. Law enforcement agencies report faster threat identification in low-light scenarios, while competitive shooters appreciate the reduced eye fatigue during extended shooting sessions. The fiber optic element remains visible even in overcast conditions where standard sights lose definition.
