TruGlo TFX TG13SG2A Tritium Fiber Optic Sight Set Green/Green

The TruGlo TFX TG13SG2A sight set combines tritium night visibility with fiber optic daylight brightness in a single aiming system. This dual-illumination technology eliminates the need to choose between low-light performance and bright daylight accuracy. The white outline front sight enhances target acquisition speed across all lighting conditions.

What Makes This Different

Unlike traditional night sights that rely solely on tritium or fiber optic sights that only work in daylight, the TFX system integrates both technologies into each sight element. The hermetically sealed capsule protects the tritium vial while channeling fiber optic light for maximum brightness. This design delivers consistent sight picture from complete darkness through bright sunlight without batteries or external light sources.

Key Features

• Dual-illumination tritium and fiber optic technology in single sight housing
• White outline front sight ring for enhanced target contrast and acquisition
• Green tritium elements provide 12-year guaranteed illumination
• Hermetically sealed construction protects internal components from moisture
• CNC-machined steel construction with nitride coating for corrosion resistance
• Snag-resistant profile reduces clothing and holster hang-ups
• Compatible with standard Glock sight installation tools

Field testing demonstrates reliable performance across temperature ranges from -20°F to 160°F. The sight picture remains consistent whether transitioning from indoor to outdoor environments or moving between shaded and brightly lit areas. Law enforcement agencies report improved first-shot accuracy during low-light qualification courses. The fiber optic elements automatically adjust brightness based on available ambient light.
