Drawing from decades of established prowess in engineering and manufacturing tritium and fiber optic aiming solutions, Trijicon introduces the Trijicon DI Night sights. With meticulous design, these sights are tailored to meet the needs of shooters who desire both the brilliance of daylight and a consistently reliable aiming point. The central innovation in the dual illuminated Trijicon DI Night sights is the industry-first, patent-pending, interchangeable fiber system. This revolutionary design allows for on-field fiber replacement and provides a variety of fiber and ring retainer colors, allowing shooters to personalize their aiming solution. Utilizing a chemical and heat-resistant fiber, utilizing the same exclusive technique found in the Trijicon ACOG, along with a tritium lamp encased with a sapphire jewel, these sights employ ingenious dual-illumination technology. This advancement effectively enhances captured light, ensuring an exceptionally bright aiming point across the entire range of lighting conditions, from broad daylight to low-light environments to complete darkness. The Trijicon DI Night sights deliver unmatched features to pistol users, enabling precise aiming in all lighting scenarios, while upholding the renowned durability and reliability that Trijicon is celebrated for. With these exceptional sights, shooters can confidently excel in any lighting condition and achieve optimal performance with their firearms.
