Truglo’s TFX sights (part no. TG13FN3A) are built for FNH FNP-45 and FNX-45 pistols. They combine Swiss tritium with fiber optics in a single sight picture, so the front sight stays bright under a fiber-optic glow by day and the tritium capsule keeps glowing after the lights go out, using a white-outlined front sight paired with a green rear sight for a fast three-dot picture.

The illuminating elements are sealed inside a chemical- and shock-resistant capsule, and the steel body carries Truglo’s rust-resistant FORTRESS finish. The design is snag-resistant and sized to work with standard holsters made for the host pistol.
