The TruGlo TG131NT3 Green Tritium/Fiber Optic front and rear handgun sights deliver unmatched target visibility for 1911 Officer-style pistols, combining durable CNC-machined metal construction with a snag-resistant design that fits most standard holsters. This green, glow-in-the-dark sight set blends Tritium and fiber optic technology to provide fast, crystal-clear sight picture across all lighting conditions, so you can acquire your target quickly without revealing your position.

No batteries are required, making these sights reliable in the field or on the range where darkness or variable light can challenge standard optics. The Truglo Tritium/Fiber Optic sight system is engineered for precision and durability, offering a seamless transition through dawn, daylight, and dusk while maintaining a robust iron sight setup suitable for everyday carry, competition, or duty use. Ideal for shooters who demand fast target acquisition, improved visibility, and dependable performance from their 1911 Officer handgun.
