The TruGlo TFO TG131GT1A combines tritium vials with fiber optic technology to deliver 24-hour sight visibility for Glock 42 and 43 pistols. This dual-illumination system provides bright daytime performance and reliable low-light operation without batteries or external light sources.
What Makes This Different
Unlike standard three-dot sights or single-technology options, the TFO system integrates both tritium gas vials and fiber optic rods in each sight post. The fiber optic elements gather ambient light during daylight hours for maximum brightness, while Swiss tritium provides consistent illumination in darkness for up to 12 years. This redundant system ensures sight visibility regardless of lighting conditions or time of day.Key Features
