XS Sights DXT2 Big Dot Night Sights Glock GL0011P3Y Tritium

The XS Sights GL0011P3Y DXT2 Big Dot Night Sights transform target acquisition speed in low-light conditions with their distinctive oversized front dot design. This sight system delivers faster sight alignment than traditional three-dot configurations through its proven big dot methodology. Shooters experience improved accuracy during rapid target transitions and stress-fire scenarios.

What Makes This Different

The DXT2 Big Dot configuration eliminates sight confusion common with standard three-dot systems by using a large tritium front sight paired with a shallow V-notch rear. This design forces proper sight alignment naturally, reducing training time and increasing hit probability. The yellow outline around the tritium insert provides enhanced visibility during daylight hours, while the white stripe rear sight creates optimal contrast for quick alignment.

Key Features

• Green tritium front sight with yellow photoluminescent outline for 24-hour visibility
• Shallow V-notch rear sight with white stripe for fast alignment
• CNC-machined steel construction with corrosion-resistant finish
• Big Dot front sight measures 0.188" diameter for rapid target acquisition
• Drop-in installation fits standard Glock sight dovetails
• Tritium rated for 10-12 year lifespan with consistent brightness
• Compatible with most holsters designed for factory Glock sights

Field testing demonstrates the DXT2 system excels in competitive shooting, law enforcement applications, and home defense scenarios. The large front dot remains visible in challenging lighting conditions where traditional sights fade, maintaining accuracy during dawn and dusk periods. The robust steel construction withstands repeated holster draws and harsh environmental conditions without losing zero or suffering finish damage.
