When you’re looking for a quality XD night sight or an XDM night sight for your Springfield or Sig pistol, there are a lot of options on the market, but few are as easy to use and durable as XS Sight Systems Big Dot Tritium Night Sights. XS sights don’t suffer from many of the issues that plague other manufacturers’ sights. Encapsulated Tritium offers durability and perfect luminescence in a sleek package that can’t be matched by battery powered sight systems and they’re built to withstand real-world field use, unlike many of their self-luminescent competitors.

When you choose an XS Sight as your next XDM night sight you’ll find your target acquisition and aim will be more intuitive and accurate than any sight you’ve tried before. XS Sights are easy to use, with a wide V-shaped sight channel and a clearly visible painted sight “post” at the rear and a perfect circle surrounding a tritium dot up front, all you have to do is dot the “I” and your sights are aligned perfectly. Put that dot on your target and fire. Whether you frequently find you­­rself in twilight or full night lighting situations, an XS Sight should be a top contender for the best sight for your next XDM night sight. The Tritium sight won’t obscure your vision with too bright light and it won’t let you down with a fade out like some luminescent sights that just don’t work well in true low light situations.

The XS Sight Systems Big Dot Tritium XDM XD Night Sight is a dependable sight that's made to work in the real world. When speed and accuracy count in low light situations this one will see you through.
