XS Sights DXT2 Big Dot Tritium Night Sights for Glock

XS Sights DXT2 Big Dot Tritium Night Sights

The DXT2 Big Dot represents the evolution of express sight philosophy—a defensive sighting system engineered for real-world gunfights where speed and clarity matter most.

Design Philosophy

Modeled after African big game hunting sights, the DXT2 system prioritizes what matters in defensive situations: a large, highly visible sight picture that works day or night. The designers understood that in most gunfights, both parties are moving and threat-focused. Your sights must be intuitive and fast.

Front Sight Technology

Photoluminescent Glow Dot: The proprietary front sight uses a patent-pending glow dot that absorbs ambient light and glows in low-light conditions—before it's dark enough to see the tritium. The convex dot design increases surface area for greater light absorption and charging intensity.

Yellow Optic Finish: Optic yellow is the optimal choice for low-light performance. Based on the white light spectrum, yellow is highly reflective and excites the photoluminescent properties faster than any other color, delivering the brightest glow intensity.

Specifications:

• Front sight dot width: 0.188"
• Overall sight height: 0.250"

Rear Sight Design

The shallow V-notch rear sight maintains a simple, low-profile design that provides an unobstructed, wide field of view. This allows you to see both your front sight and the threat downrange clearly.

The Dot-the-"i" Sight Picture

The tritium dot in front paired with a tritium bar in the rear creates a distinctive sight picture that prevents confusion in high-stress situations. You'll instantly know which sight is which, even under pressure.

Compatibility

Fits Glock 17, 19, 22, 23, 24, 26, 27, and 31 (Gen 1-5).

Why Big Dot Sights?

Large sights solve real problems: aging eyes, vision changes, and the need for speed. The DXT2 Big Dot is big, bright, and easy to see—whether you're shooting in daylight or darkness.
