The TruGlo TGTG13NV4A TFX Black is a high-contrast front and rear sight set designed for fast, reliable aiming with 1911-style handguns, featuring a compact snag-free design, longer sight radius, and a rugged CNC-machined steel construction finished in a rust-proof Fortress Finish. Illuminating elements are encased in an indestructible capsule, delivering brilliant green Tritium plus Fiber-Optic performance by day and night, with the front sight boasting a highly visible white-outlined ring to rapidly draw the eye to the target, while the rear pairs a green Tritium and Fiber Optic profile for a clear three-dot sight picture. These TFX sights are impervious to oils, solvents, and even ultra-sonic cleaning, ensuring enduring brightness and reliability 24/7 without batteries, making them ideal for fast target acquisition in varied lighting. The concealed fiber cannot be seen by the target, and the snag-resistant design and Novak LoMount cut compatibility for 1911 frames with the appropriate dovetail ensure seamless installation and fit, with the performance you expect from Truglos award-winning technology.
