The TruGlo TFO TG131GT1B sight set combines tritium and fiber optic technology to deliver 24-hour visibility for Glock 42 and 43 pistols. This dual-illumination system automatically transitions from bright fiber optic performance in daylight to tritium glow in low-light conditions.
What Makes This Different
The TFO (Tritium Fiber Optic) design eliminates the visibility gaps found in standard sights by incorporating both illumination technologies in a single sight body. While traditional night sights rely solely on tritium and become dim during daylight hours, this system maintains bright visibility across all lighting conditions. The green front sight provides rapid target acquisition, while the yellow rear sight creates optimal contrast separation.Key Features
