The TruGlo TG13SG1A TFX Pro night sights deliver 24-hour visibility with dual-illumination technology that combines tritium gas capsules with fiber optic elements. This sight set provides consistent aiming reference in any lighting condition, from bright daylight to complete darkness.
What Makes This Different
The TFX Pro series integrates both tritium and fiber optic illumination in a single sight housing, eliminating the need to choose between daylight brightness and low-light capability. The white focus-lock ring on the front sight creates faster target acquisition compared to standard three-dot configurations. Swiss tritium lamps maintain brightness for 12 years, while the fiber optic elements gather ambient light during daylight hours.
Key Features
- Green tritium gas lamps with 12-year brightness guarantee
- Fiber optic technology for enhanced daylight visibility
- White focus-lock ring on front sight for rapid target acquisition
- CNC-machined steel construction with protective coating
- Snag-resistant design with angled rear edges

Field testing demonstrates consistent point-of-impact accuracy across temperature ranges from -20°F to 120°F. The sight picture remains clear in rain, snow, and humid conditions due to the sealed tritium capsules and weather-resistant fiber optic housing. Competition shooters report faster split times compared to standard iron sights, while duty officers appreciate the consistent sight picture during high-stress scenarios.
