AmeriGlo SG301 i-Dot Night Sights SIG Sauer Green Tritium Set

The AmeriGlo SG301 i-Dot sight set transforms SIG Sauer pistols with a precision three-dot configuration that excels in all lighting conditions. This sight system combines self-illuminating tritium vials with high-contrast outlines for rapid target acquisition day or night.

What Makes This Different

The i-Dot configuration features a distinctive front sight design with a green tritium dot surrounded by a bright LumiGreen photoluminescent outline that charges from ambient light. Unlike standard white dot sights that disappear in low light, this system provides consistent sight picture across varying conditions. The rear sight incorporates two green tritium dots that create perfect alignment with the front sight for intuitive aiming.

Key Features

• Self-illuminating green tritium vials with 12-year guaranteed brightness
• LumiGreen photoluminescent front sight outline charges from ambient light
• Precision-machined steel construction with corrosion-resistant finish
• Drop-in replacement for factory SIG Sauer sights
• Three-dot configuration for fast sight alignment
• Professional installation recommended for optimal zero
• Compatible with most SIG Sauer pistol holsters

Field performance demonstrates the advantage of dual-illumination technology during transition periods when ambient light changes rapidly. Law enforcement and competitive shooters report faster target acquisition compared to single-illumination systems. The steel construction maintains zero through repeated firing cycles and environmental exposure, while the tritium maintains consistent brightness regardless of weather conditions.

Technical Specs

• Front sight: Green tritium with LumiGreen outline
• Rear sight: Dual green tritium dots
• Material: Precision-machined steel
• Tritium life: 12-year manufacturer guarantee
