XS Sights DXT2 Big Dot Night Sights Sig Sauer SI0014S5Y Tritium

The XS Sights DXT2 Big Dot Night Sights deliver rapid target acquisition in any lighting condition with their distinctive oversized front dot design. These tritium-powered sights eliminate the guesswork in low-light scenarios while maintaining precision accuracy for daylight shooting.

What Makes This Different

The DXT2 system combines a large .188-inch tritium front dot with a shallow V-notch rear sight, creating faster sight alignment than traditional three-dot configurations. The yellow outline front sight provides maximum contrast against dark targets, while the white outline rear bar ensures consistent sight picture. This design reduces sight alignment time by up to 30% compared to standard dot configurations.

Key Features

• Green tritium front dot with bright yellow photoluminescent outline for rapid acquisition
• Green tritium rear sight with white outline bar for precise alignment
• Big Dot front sight measures .188 inches for enhanced visibility
• Shallow V-notch rear design eliminates dot confusion in stress situations
• CNC machined from bar stock steel with matte black finish
• Direct fit for Sig Sauer P-series pistols with standard dovetail cuts
• Self-illuminating tritium vials rated for 10-year minimum brightness

Field performance centers on the Big Dot philosophy of point shooting accuracy combined with precision sight alignment capability. The oversized front sight naturally draws the eye for instinctive shooting at close range, while the rear sight provides the reference point needed for precision shots at distance. Law enforcement and competitive shooters report improved split times and target transitions with the DXT2 system. The tritium illumination maintains consistent visibility in dawn, dusk, and indoor environments without requiring batteries or external light sources.
