XS Sights DXT2 Big Dot Night Sights Glock GL0009S5N Tritium

The XS Sights GL0009S5N DXT2 Big Dot delivers faster target acquisition in low-light conditions with its oversized front dot design. This sight system combines green tritium illumination with high-contrast colored outlines for superior visibility across all lighting conditions.

What Makes This Different

The DXT2 Big Dot features an enlarged front sight dot that's 30% larger than standard three-dot systems, creating an instinctive point-and-shoot sight picture. The orange outline front sight paired with the white outline rear bar creates maximum contrast against dark backgrounds. Green tritium inserts provide 12-year illumination without batteries or external power sources.

Key Features

• Big Dot front sight with green tritium and orange outline for rapid acquisition
• Express-style rear sight with green tritium and white outline bar
• CNC-machined from bar stock steel with matte black finish
• Fits standard Glock dovetail cuts without modification
• Swiss tritium lamps rated for 12-year brightness guarantee

The DXT2 system excels in defensive shooting scenarios where speed matters more than precision. Law enforcement and concealed carry users benefit from the intuitive sight alignment that works under stress.
