Drawing upon decades of established engineering and manufacturing expertise in tritium and fiber optic aiming solutions, Trijicon introduces the Trijicon DI Night sights. These sights are meticulously designed to cater to shooters seeking both daylight brightness and a consistently reliable aiming point. The key innovation in the dual illuminated Trijicon DI Night sights is the industry-first, patent pending, interchangeable fiber system. Notably, this ground breaking design allows for on-field fiber replacement and offers the flexibility to select from various fiber and ring retainer colors, enabling shooters to personalize their aiming solution. Trijicon DI Night sights incorporate a chemical and heat resistant fiber, utilizing the same exclusive technique found in the Trijicon ACOG. Complementing this is a tritium lamp encased with a sapphire jewel. The ingenious dual-illumination technology effectively enhances gathered light, ensuring an exceptionally bright aiming point across the entire spectrum of lighting conditions, from broad daylight to dim environments to complete darkness. The Trijicon DI Night sights provide pistol users with unmatched features for precise aiming in all lighting scenarios, while upholding the renowned durability and reliability that Trijicon is celebrated for.
