The TruGlo TFX Handgun Sights Glock SUP High Set from Truglo deliver bright daytime and nighttime visibility with their advanced Tritium plus Fiber-Optic technology, featuring a compact snag-free design that lengthens the sight radius and stands up to harsh use with a virtually indestructible capsule and a rust-proof Fortress Finish. Illuminating elements are safeguarded within a durable, shock-resistant enclosure, and a highly visible white ring around the front fiber helps the eye lock onto the front sight for a fast, accurate sight picture in any shooting condition. Built to impress discerning shooters, these sights are impervious to oils, chemicals, cleaning solvents, and ultra-sonic cleaning processes while maintaining unmatched 24/7 visibility. The concealed fiber remains unseen by the target, ensuring stealthy presentation, and the Snag Resistant design preserves reliability across gear changes and holster draws. With Swiss-grade tritium for maximum brightness and a patent-protected, precision-machined profile, the Truglo TFX Handgun Sights offer a durable, maintenance-friendly upgrade that enhances accuracy, speed, and confidence in every encounter.
