HiViz GLMFD21 FastDot H3 Glock MOS Sight Set Red Fiber Green Tritium

The HiViz GLMFD21 FastDot H3 sight set transforms target acquisition speed on Glock MOS pistols through its dual-illumination design. This sight combination delivers rapid target engagement in all lighting conditions with a bright red fiber optic front sight paired with green tritium rear sights.

What Makes This Different

The FastDot design features a larger front sight dot that creates faster sight alignment compared to standard three-dot configurations. The red fiber optic front sight gathers ambient light during daylight hours while the green tritium rear sight provides consistent illumination in low-light conditions. This contrasting color combination reduces sight confusion and improves target acquisition speed by up to 30% over traditional same-color sight systems.

Key Features

• Red fiber optic front sight with replaceable LitePipe for maximum brightness
• Green tritium rear sight with 12-year guaranteed illumination
• FastDot configuration reduces sight alignment time
• Direct fit for Glock MOS (Modular Optic System) pistols
• Steel construction with corrosion-resistant finish
• Standard height maintains holster compatibility
• Tool-free LitePipe replacement system

The sight set performs consistently across temperature ranges from -40°F to 150°F without losing zero or brightness. Competition shooters report improved split times in USPSA and IDPA matches, while law enforcement officers benefit from the enhanced visibility during low-light encounters. The contrasting red-green color scheme works effectively for shooters with various forms of color vision deficiency.
