XS Sights DXT2 Big Dot Night Sights Glock GL0010S5N Tritium

The XS Sights GL0010S5N DXT2 Big Dot Night Sights deliver faster target acquisition in low-light conditions with their distinctive oversized front dot design. These tritium-powered sights eliminate the guesswork of traditional three-dot systems by providing a clear, instinctive sight picture that works in complete darkness.

What Makes This Different

The DXT2 Big Dot system uses a single large tritium front sight paired with a shallow V-notch rear, creating an intuitive sight alignment that's 39% faster than standard three-dot configurations. The front sight features green tritium with a bright orange photoluminescent ring that charges from ambient light, while the rear sight uses a white outline bar design that frames the front dot perfectly. This configuration reduces visual clutter and allows shooters to focus on the threat rather than aligning multiple reference points.

Key Features

• Big Dot front sight with green tritium insert and orange photoluminescent outline ring
• Shallow V-notch rear sight with green tritium and white outline for precise framing
• Swiss tritium vials rated for 10-12 years of continuous illumination
• CNC-machined from bar stock steel with matte black finish
• Drop-in replacement for factory Glock sights on most models
• Front sight height: 0.180 inches, rear sight height: 0.165 inches
• Designed for defensive shooting scenarios requiring rapid target engagement

Field performance testing shows the DXT2 system excels in high-stress situations where traditional sight alignment becomes difficult. The large front dot remains visible in varying light conditions, from bright daylight to complete darkness. Law enforcement agencies report improved accuracy during qualification courses, particularly in timed fire exercises. The sight picture works effectively at defensive distances from contact range to 25 yards, making it suitable for concealed carry, duty use, and home defense applications.
