Truglo TG131NTI Green Tritium Fiber Optic Front Rear Sights for 1911

The TruGlo TG131NTI TFO Green/Tritium/Fiber Optic front and rear sights combine patented Tritium and fiber-optic technology to deliver a consistently bright sight picture in any lighting condition, ensuring fast, accurate shots from dawn to dusk. Built with CNC-machined steel and designed to be snag-resistant, these Novak LoMount-cut sights are engineered for reliability on 1911 Government models and Ruger SR1911 variants, including the 5" .45 ACP configurations, with front .260 and rear .450 dovetails. The concealed fiber optimization provides a clear, high-contrast glow without giving away your position, while the green tritium and fiber-optic mix offers an intuitive sight picture that transitions seamlessly as lighting shifts. The system requires no batteries, and its rugged construction fits standard holsters for practical daily carry and duty use. Truglo's design also notes that yellow fiber optics are intended to appear less bright than green to enhance front-rear sight contrast, further improving fast acquisition in dynamic environments. Installation is best performed by a competent gunsmith to preserve fit on Novak LoMount cuts, and once installed, these sights offer a reliable, bright reference that makes quick, precise transitions possible in bright daylight or total darkness, supporting responsible, confident handgun performance.
