Leveraging the award-winning Tritium + Fiber-Optic technology, TFX sights elevate performance with a compact, snag-free design, extended sight radius, and unparalleled durability. Encased within a virtually indestructible, chemical and shock-resistant capsule, the illuminating elements withstand the harshest conditions, while the CNC-machined steel, fortified with a rust-resistant Fortress Finish, ensures lasting resilience.

Designed to fit standard holsters, TFX sights, with a fiber diameter of 0.074", offer exceptional performance in any lighting environment.
