Frequently Asked Questions
How do Trijicon DI Night Sights differ from standard tritium night sights?
Standard tritium night sights rely solely on radioactive tritium gas to glow in the dark, which can appear dim in daylight. Trijicon DI (Dual Illumination) Night Sights add a fiber optic element that collects and amplifies ambient light, producing a significantly brighter aiming point during daylight and transitional lighting. At night or in darkness, the tritium lamp takes over, ensuring you always have a visible aiming point without any batteries or electronics.
Are these sights compatible with all Glock models?
These Trijicon DI Night Sights are designed specifically for Glock Standard Frame pistols, which includes popular models such as the Glock 17, 19, 22, 23, 34, and 35, among others. They are not intended for Glock Slim Frame (single-stack) or MOS models with optics-ready cuts. Always verify your specific Glock generation and frame size before purchasing to ensure proper fitment.
Can I replace the fiber optic myself, and are replacement fibers available in other colors?
Yes — one of the standout features of the Trijicon DI Night Sights is their patent-pending interchangeable fiber design, an industry first. The fiber can be swapped out in the field without special tools, and Trijicon offers replacement fibers and ring retainers in multiple colors. This allows you to customize your front sight color to match your preference or shooting discipline long after your initial purchase.
