The TruGlo TG13FN3A TFX Black front and rear handgun sights deliver unmatched 24/7 visibility with Green Tritium and Fiber Optic White Outline for rapid target acquisition in any light condition, thanks to the patented TFX technology that is fully protected in an almost indestructible configuration. These sights utilize quality Swiss tritium for maximum brightness, glow in the dark without batteries, and feature concealed fiber that cannot be seen by the target, preserving a clean sight picture. Built to endure harsh environments, the Fortress Finish provides a permanent protective coating that resists oils, chemicals, cleaning solvents, and ultra-sonic cleaning processes, ensuring long-lasting performance. The snag-resistant design enhances draw and transition, while the sight design remains compatible with standard holsters, offering practical versatility for daily carry and duty use. Crafted by Truglo, this system combines front and rear sights with a durable, maintenance-friendly build that supports precise aiming in competitions, personal defense, and outdoor hunting scenarios, delivering dependable brightness and reliability when it matters most.
