XS Sights GL0015P5Y DXT2 Big Dot Tritium Night Sights for Glock

The XS Sights GL0015P5Y DXT2 Big Dot Night Sights transform low-light shooting accuracy with an oversized front sight dot that catches the eye instantly. This tritium-powered sight system delivers 24/7 visibility without batteries or external light sources, making target acquisition faster in critical situations.

What Makes This Different

The DXT2 system features an enlarged front sight dot that measures significantly larger than standard three-dot configurations, creating faster sight alignment under stress. The yellow outline around the green tritium front sight provides maximum contrast against varied backgrounds, while the rear sight's white outline bar creates a clean sight picture. This design eliminates the confusion of aligning multiple dots common with traditional sight systems.

Key Features

• Big Dot front sight with green tritium insert and yellow photoluminescent outline
• Express-style rear sight with green tritium bar and white outline
• Self-illuminating tritium rated for 12+ years of continuous visibility
• Steel construction with anti-reflective black finish
• Direct replacement for factory Glock sights on most models
• Shallow V rear notch optimized for Big Dot alignment
• Photoluminescent outlines charge from ambient light

The DXT2 sight system excels in defensive scenarios where split-second target acquisition matters most. Law enforcement and concealed carry users benefit from the intuitive sight picture that works effectively from contact distance to 15 yards. The large front dot naturally draws focus while the rear bar provides precise elevation reference. Weather resistance comes from the steel construction and sealed tritium capsules that maintain brightness in rain, snow, or extreme temperatures.
