Frequently Asked Questions
How do the Trijicon DI Night Sights perform in bright daylight versus complete darkness?
In daylight, the fiber optic element collects and amplifies ambient light to create an ultra-bright aiming point that's easy to pick up quickly on target. As light fades into low-light or total darkness, the tritium lamp — sealed beneath a scratch-resistant sapphire jewel cap — takes over, providing a self-luminous green glow with no batteries required. This seamless transition is what sets the dual-illumination system apart from purely fiber optic or purely tritium sights.
Are these sights a direct drop-in fit for both the Glock 42 and Glock 43?
Yes. The Trijicon DI Night Sights in this listing are engineered specifically for the Glock 42 and Glock 43 platform. They use the standard Glock dovetail dimensions and are designed for a precise, tool-assisted installation with a sight pusher tool — no gunsmithing or permanent modification is required. Always verify your exact model and generation before purchasing to ensure compatibility.
Can I replace or change the fiber optic myself, and what colors are available?
Absolutely. The Trijicon DI Night Sights feature an industry-first interchangeable fiber design that allows you to swap out the fiber optic element in the field without special tools. This patent-pending system also lets you select from multiple fiber colors and ring retainer colors, so you can customize your sight picture to match your preference or shooting environment. Replacement fibers are available separately from Trijicon.
