XS Sights SW0019S3 DXW Big Dot Night Sights Smith & Wesson Green Tritium

The XS Sights SW0019S3 DXW Big Dot Night Sights deliver rapid target acquisition in any lighting condition for Smith & Wesson pistols. This tritium sight system combines a large front dot with a rear sight designed for quick alignment and consistent accuracy.

What Makes This Different

The Big Dot front sight measures significantly larger than standard three-dot systems, creating faster sight picture acquisition under stress. Green tritium illumination provides 12-year visibility without batteries or external light sources. The white outline around the front sight enhances contrast during daylight shooting, while the rear sight's white stripe creates a clear sight picture reference.

Key Features

• Green tritium front sight with white outline for 24/7 visibility
• Oversized front dot design for rapid target acquisition
• White stripe rear sight for consistent alignment
• 12-year tritium half-life with Swiss-made vials
• CNC-machined steel construction with protective coating
• Drop-in replacement for factory Smith & Wesson sights
• Designed for defensive shooting applications

These sights excel in low-light defensive scenarios where speed matters more than precision. The Big Dot system reduces sight alignment time by eliminating the need to center a small dot within a rear notch. Law enforcement and concealed carry users benefit from the simplified sight picture that works effectively at typical defensive distances of 3-15 yards.
