TruGlo TG131NT2 TFO Tritium Fiber Optic Sight Set 1911 Government

The TruGlo TG131NT2 TFO sight set delivers 24-hour visibility through its innovative tritium and fiber optic combination technology. This dual-illumination system automatically adapts to lighting conditions, providing bright fiber optic performance in daylight and reliable tritium glow in darkness without batteries or external power sources.

What Makes This Different

The TFO (Tritium Fiber Optic) design combines two proven sight technologies into a single, self-contained unit. Unlike traditional night sights that only function in low light, or fiber optic sights that fade in darkness, this system maintains consistent visibility across all lighting conditions. The Swiss tritium vials are rated for 12 years of continuous illumination, while the fiber optic elements gather ambient light for enhanced daytime brightness.

Key Features

• Dual illumination system combines tritium and fiber optic technology
• Swiss tritium vials provide 12-year guaranteed illumination
• CNC-machined steel construction with protective sight ring
• Direct replacement for factory 1911 Government model sights
• Green front and rear sight configuration for fast target acquisition
• Snag-resistant profile designed for concealed carry
• No batteries or maintenance required for operation

Field performance testing demonstrates consistent point-of-impact accuracy across temperature ranges from -20°F to 120°F. The sight set maintains zero through repeated firing sessions and handles recoil from standard .45 ACP loads without shift. Law enforcement agencies report reliable function in duty conditions, while competitive shooters note the improved sight picture speed in varying match lighting.
