The TruGlo TFX Handgun Sights Glock SUP Low Set from Truglo deliver bright, reliable visibility day and night with our advanced TFX technology that combines Tritium and fiber-optic elements in a compact, snag-free design built to extend the sight radius and withstand demanding use, while the virtually indestructible capsule preserves illumination and the rust-proof Fortress Finish protects the CNC-machined steel. A highly visible white ring around the front fiber enhances focus on the front sight for a fast, precise sight picture, and the concealed fiber remains unseen by the target, helping you maintain a clean silhouette during rapid target acquisition. These sights are designed to be impervious to oils, solvents, and cleaning processes, ensuring consistent performance in harsh conditions without batteries or maintenance concerns. With unmatched visibility in all lighting and 24/7 reliability, the TruGlo TFX Handgun Sights Glock SUP Low Set empower skilled shooters and hunters to execute fast, accurate shots in any environment, while maintaining compatibility with standard holsters for seamless everyday carry and use.
