The XS Sights DXT2 Standard Dot Tritium Night Sights are purpose-built for shooters who need reliable sight acquisition in everything from bright daylight to near-total darkness. If you carry a Glock 43 and want a night sight that performs without compromise across changing light conditions, the DXT2 delivers a straightforward, stress-tested sight picture when it matters most.

The core of the DXT2 design is simplicity: a tritium-filled dot on the front sight paired with a tritium bar on the rear. This "dot-the-I" configuration eliminates confusion during high-stress situations—your eye naturally centers the dot in the rear notch, and the sight picture stays intuitive. The front sight features a photoluminescent glow dot that absorbs ambient light and glows visibly in low-light conditions before the tritium vials take over in near-darkness. XS Sights engineered the convex dot with a larger surface area to maximize light absorption and boost glow brightness, especially valuable in those twilight moments when you need to see your sights but haven't yet entered true darkness.

The optic orange coating on the front sight is where daylight performance shines. That orange-yellow-red blend delivers high contrast in bright sunlight, then shifts to rely more on yellow tones as ambient light drops, maintaining a visible sight picture through the transition into evening. The low-profile V-notch rear sight opens up your field of view, keeping your eyes focused on the front sight and your target rather than trapped in the rear sight geometry. Installation is direct: these sights fit Glock 43 pistols without modification.

Frequently Asked Questions

Will the DXT2 sights work in complete darkness?

Yes. The tritium vials glow continuously without external charging and remain visible in total darkness. The photoluminescent glow dot provides an additional bright reference point when ambient light is available; in darkness, the tritium takes over.

What is the glow dot and how does it work?

The glow dot is a photoluminescent element on the front sight that absorbs ambient light during the day and early evening, then glows visibly in low-light conditions before it becomes dark enough for the tritium to be your primary aiming reference. This bridges the gap between daylight and night shooting.

Do these sights fit my Glock 43?

Yes. The XS Sights DXT2 Standard Dot is designed to fit Glock 43 pistols without modification.

How is the optic orange finish different from standard tritium sights in bright light?

The optic orange coating creates high contrast in daylight conditions, making the front sight pop against most backgrounds. The orange-yellow-red blend shifts to rely more on yellow as light dims, maintaining sight visibility through the transition from day to dusk without requiring a separate sight picture adjustment from the shooter.
