XS Sights DXT2 Big Dot Night Sights Glock GL0011S5Y Tritium

The XS Sights GL0011S5Y DXT2 Big Dot Night Sights deliver fast target acquisition in any lighting condition for Glock pistols. These professional-grade sights combine tritium illumination with high-contrast outlines to create an intuitive sight picture that speeds up defensive shooting scenarios.

What Makes This Different

The DXT2 system features an oversized front dot that draws the eye naturally, eliminating the need to line up traditional three-dot configurations. While standard night sights require precise alignment of multiple points, the Big Dot design allows shooters to simply drive the large front sight to the target. The shallow V-notch rear sight with white outline bar creates a clear window that frames the front dot perfectly.

• Shallow V-notch rear sight with green tritium and white outline bar

Field testing demonstrates the DXT2's effectiveness across multiple shooting disciplines. Law enforcement agencies report faster engagement times during low-light qualifications, while competitive shooters appreciate the consistent sight picture under match pressure. The tritium remains visible in complete darkness, while the photoluminescent outlines charge from ambient light sources. Weather sealing protects the tritium vials from moisture and impact during extended carry.
