XS Sight Systems DXT2 PRO Big Dot Green Tritium Night Sights for S&W CSX

The XS Sight Systems DXT2 PRO Big Dot night sight set is purpose-built for the Smith & Wesson CSX pistol, pairing an oversized front tritium dot with a simplified rear V-notch for fast, intuitive sight acquisition in defensive and everyday-carry use.

The front sight carries XS's signature 0.188" Big Dot with a green tritium glow dot, engineered for high contrast in bright light and a bright, reliable glow in low light. The rear sight uses a clean V-notch framing a vertical white line, drawing the shooter's eye directly to the front dot for rapid target acquisition under stress.

Both the front and rear sights are CNC machined from steel and finished in Black Nitride for excellent corrosion resistance and long-term durability under hard daily carry. The set is tritium-equipped front and rear, giving shooters a daylight-bright aiming reference that doubles as a dependable low-light sight picture.

Designed specifically as a direct-fit replacement for factory sights on the S&W CSX platform, the DXT2 PRO Big Dot set is a fast, rugged upgrade for CSX owners who want the Big Dot sight picture trusted by defensive and EDC shooters.

Your purchase includes the DXT2 PRO Big Dot front sight and rear sight, ready to install on your Smith & Wesson CSX.
