XS Sights DXT2 Big Dot Night Sights for Glock - Black | Green Tritium Yellow Front, Green Tritium White Rear

The XS Sights DXT2 Big Dot night sights for Glock are purpose-built for shooters who need to get on target fast—whether you're training at the range, carrying for self-defense, or running low-light drills. These tritium night sights combine a large, illuminated front dot with XS's proven rear-sight design to encourage the front-sight focus that breeds speed and accuracy when it matters. The big dot front sight glows in complete darkness and features a photoluminescent ring that bridges the gap when transitioning between bright and low-light environments, so you're never left squinting at your sights.

Built for compact carry guns, these DXT2 sights fit Glock G42 and G43 models and sit lower in their shallow rear notch, giving you a wider field of view for faster target acquisition at defensive distances. The "dot the i" aiming concept is straightforward: center the glowing front dot in the rear notch and press the trigger. No complicated reticles, no parallax worries—just instinctive, repeatable sight alignment. The sights are constructed to handle everyday carry and will work with standard Glock holsters, though the dovetail fit may require minor filing depending on your gun's tolerances.

If you carry a small-frame Glock or use one for personal protection, upgrading from factory plastic sights to tritium night sights is one of the smartest defensive modifications you can make. XS Sights has built a solid reputation in the carry and duty gun market, and the DXT2 delivers proven performance in the size and configuration that works for sub-compact shooters.

Frequently Asked Questions

Will these XS Sights DXT2 night sights fit my Glock?

These sights are designed for Glock G42 and G43 models. They use a standard dovetail fit and are compatible with common Glock holsters, though you may need to file the dovetail slightly for a perfect fit depending on your gun's tolerances.

How do the tritium and photoluminescent ring work together?

The tritium lamp glows continuously in the dark without needing a battery. The photoluminescent ring around the front dot absorbs light during the day and bridges visibility when you move from bright to dim lighting. Together, they ensure your sights are usable in any light condition—from bright daylight to total darkness.

Are these sights designed for close-range or long-range shooting?

The DXT2 Big Dot design is optimized for rapid aiming at targets inside 15 yards, making them ideal for self-defense, carry, and close-range tactical training rather than precision rifle-style long-distance work.

What does "dot the i" mean?

It's XS Sights' way of describing the aiming concept: center the big illuminated front dot in the rear notch (like dotting an lowercase "i") and press the trigger. It's a simple, instinctive sight picture designed for speed.
