XS Sights Introduces the DXT2 Big Dot Night Sights

Building on the success of the original XS Big Dot night sights, XS Sights has introduced the new DXT2 Big Dot night sights. XS has added a new high contrast front dot that is four times brighter in low light than the outgoing original Big Dot sights.


The new DXT2 sights will be available in two colors, Optic Yellow and Optic Orange that will be paired with a large tritium vial in the front sight. The rear sight will still feature that vertical tritium lamp that Big Dot users have become accustomed to.


The new XS Sights DXT2 Big Dot sights will be available for Glocks, S&W M&P, S&W Shield, Sig P-Series, Springfield XD, and the FN 509 in December of 2018. MSRP for the new sights will be $132, learn more on the XS Sight website.

XS® Sights is pleased to introduce the new DXT2™ Big Dot® Night Sights for exceptional front sight visibility in all lighting conditions. Available in two colors – Optic Yellow™ and Optic Orange™ – the DXT2 Big Dot sights drive focus to the front sight (and thus to the downrange threat) using a large, high-contrast front and a V-notch rear sight for an unobstructed view of the front sight.

The Big Dot front sights use a patent-pending colored glow dot that absorbs light, causing the sight to glow before it is dark enough to see the tritium center. The glow dot also stores energy enabling it to glow brightly for many hours. The V-notch rear sight features a vertical white stripe with a tritium vial at the center, creating a dot-the- “i” sight picture for fast and accurate target acquisition in high-stress situations.

“Our DXT2 Big Dot Night Sights are the most visible night sights on the market today for defensive shooting,” said Zack Kinsley, Marketing Manager for XS Sights. “The industry-leading large diameter front sight increases the amount of light that is absorbed and reflected to the eye. The yellow and orange color options we offer address different needs, since color perception can vary greatly between people.”

Optic Yellow is the most visible color in low light and is a direct replacement for the first-generation white Big Dot sight. In bright light, Optic Yellow outperforms white because it doesn’t wash out on light backgrounds. Optic Orange is the best for bright light settings such as shooting outside in daylight and offers a high-glow intensity that maintains visibility in decreasing light levels. These Gen 2 Big Dots are four times as bright in low light as the Gen 1 Big Dots thanks to the XS Sights patent-pending glow dot. This increased brightness is due to pairing the convex dot with photoluminescent properties. The outward curve of the dot increases the amount of surface area, exposing the dot to more light, and the optical clarity amplifies light absorption, which increases the excitement of the photoluminescent properties.

DXT2 Big Dot Night Sights are backed by a 10-year, no questions asked warranty and will be available for the following pistol models by December 2018:

  • All Glocks
  • S&W M&P Full-size/Compact
  • S&W M&P Shield
  • SIG SAUER P Series (P320, P226, P229)
  • Springfield XD Series
  • FNH FN509
