HiViz FastDot H3 Sight Set for Glock MOS

HiViz FastDot H3 Night Sight System

The HiViz FastDot H3 represents a thoughtful approach to pistol sighting. This low-profile sight system merges fiber optic and tritium technology to deliver reliable illumination in any lighting condition—from bright daylight to complete darkness.

Key Features

• Dual-Illumination Design: Red fiber optic front sight captures ambient light; green tritium rear sight glows independently in low light
• 24-Hour Visibility: Fiber optics work in daylight; tritium provides nighttime illumination without external power
• Low-Profile Construction: Fits standard holsters and reduces snag risk
• All-Steel Build: Durable construction withstands regular use and training
• Patented Technology: HiViz's proven sight design refined for modern pistols

Compatibility

Designed specifically for all Glock MOS (Modular Optic System) pistols chambered in:

• 9mm
• .40 S&W
• .357 Sig

Warranty & Safety

HiViz backs these sights with a 12-year tritium warranty against failure due to defects in materials or workmanship during normal use. The tritium gas is regulated by the US Nuclear Regulatory Commission; purchasers are exempt from regulatory requirements. Do not attempt to disassemble the sight.

Why Choose This System

Whether you're training at the range or carrying for personal defense, the FastDot H3 ensures you can acquire your target quickly and accurately in any light. The combination of bright fiber optics and self-illuminating tritium makes this a practical choice for shooters who demand reliability.
