The Truglo TFX Handgun Sights Smith & Wesson M&P Set from Truglo delivers bright, reliable illumination in any light with its advanced Tritium + Fiber-Optic technology, encased in a nearly indestructible capsule for rugged, long-lasting performance. This compact, snag-free design extends the sight radius for quicker target acquisition while the CNC-machined steel is protected by the rust-proof Fortress Finish, ensuring durable service in demanding environments. Illuminating elements stay visible from day to night, and a highly visible white ring around the front fiber enhances rapid front-sight focus for a fast, accurate sight picture. The TFX configuration is impervious to oils, chemicals, cleaning solvents, and even ultra-sonic cleaning processes, making it a practical choice for daily carry and range use alike. With no batteries required, the front fiber remains concealed from the target while delivering superior visibility in all shooting conditions. Patented and designed to fit standard holsters, these Truglo sights are built to withstand harsh handling and deliver dependable performance across a variety of lighting scenarios for Smith & Wesson M&P pistols.
