HiViz FastDot H3 Sight Set for SIG P320/P365

HiViz FastDot H3 Night Sight System

The HiViz FastDot H3 represents a thoughtful approach to pistol sighting systems. This low-profile sight set merges fiber optic and tritium technologies to deliver reliable illumination in all light conditions—from bright daylight to complete darkness.

Key Features

• Dual Illumination System: Red fiber optic front sight captures ambient light; green tritium rear sight glows independently in low light
• 24-Hour Visibility: Fiber optic works in daylight; tritium provides nighttime illumination without external power
• Low-Profile Design: Maintains standard holster compatibility while keeping sight height at factory specifications
• All-Steel Construction: Built to withstand the rigors of regular shooting and carry
• Patented Technology: HiViz's proven sight design refined for modern pistol platforms

Specifications

• Front Sight: 0.980" length × 0.155" width × 0.207" height
• Rear Sight: 0.780" length × 0.650" width × 0.240" height
• Compatibility: SIG P320 and P365 in 9mm with fixed sights only (non-optic ready models)
• Warranty: 12-year tritium luminosity warranty against defects in material and workmanship

Important Notes

This sight set is designed for fixed-sight pistols only and cannot be mounted on optic-ready models or pistols with mounted optics. The tritium component is regulated by the US Nuclear Regulatory Commission; the purchaser is exempt from regulatory requirements. Do not attempt to disassemble the sight.

The FastDot H3 delivers the reliability and visibility serious shooters demand, whether you're training at the range or carrying for personal protection.
