XS Sights DXT2 Night Sight Set for Glock 42/43/43X/48 - Big Dot Tritium Front & Tritium Stripe Rear

The XS Sights DXT2 Night Sight Set for Glock 42/43/43X/48 is purpose-built for shooters who need reliable sight acquisition in any light. Whether you're training in dimly-lit indoor ranges, carrying for self-defense, or hunting in low-light conditions, this big dot tritium front and rear sight combo delivers the speed and confidence that matter when you press the trigger. The DXT2 design puts the emphasis where it counts: on a fast, intuitive sight picture that works whether the sun is high or the range has gone dark.

The front sight's oversized convex dot absorbs ambient light exceptionally well, producing a visible glow in twilight before tritium activation becomes necessary. The Optic Orange finish on the front creates a high-contrast reference in bright daylight—that same orange transitions effectively as light fades, maintaining a visible sight picture without relying entirely on tritium until darkness truly sets in. The V-notch rear sight keeps your field of view wide and uncluttered, reducing visual noise when you're focused on the threat or target. The tritium stripe on the rear and tritium dot on the front establish a clean, intuitive "dot-the-i" sight alignment that's easy to find under stress and leaves no room for confusion about which sight is which.

This is a complete sight set engineered for the compact Glock 42, single-stack Glock 43, and the slightly larger Glock 43X and Glock 48. If you carry a modern micro-compact or sub-compact Glock and you want sights that work around the clock—not just when conditions are ideal—this is the setup to trust.

Frequently Asked Questions

Will the XS DXT2 sights work on my Glock 42, 43X, or 48?

Yes, this sight set is designed to fit Glock 42, 43, 43X, and 48 models. Confirm your specific Glock model before ordering if you're unsure of your platform.

Do these sights glow in the dark without tritium activation?

The front sight's oversized dot absorbs and glows in low-light conditions before it gets dark enough for tritium to become the primary light source. This hybrid approach gives you visibility across a wider range of lighting conditions than tritium alone.

What does "dot-the-i" sight picture mean?

The front sight features a tritium dot, and the rear sight has a tritium bar or stripe. You align the dot on top of the bar, much like dotting the letter "i"—an intuitive, fast sight picture that's easy to find and hold under stress.

Is this a complete sight set, or do I need to buy additional components?

This is a complete set that includes both the front and rear sights needed to replace your factory Glock sights.
