DXT2 Big Dot Night Sights

XS DXT2 Big Dot Night Sights

See Your Sights Day and Night!

 DXT2 Big Dot Night Sights offer the best front sight visibility in all lighting conditions. DXT2 Big Dot sights drive focus to the front sight using a high-contrast front and a V-notch rear for an unobstructed view of the front sight. DXT2 Big Dot front sights use our Ember glow dot that absorbs light and glows in low light levels before it is dark enough to see the tritium. The dot-the-“i” sight picture prevents confusing the front and rear sights in high-stress situations.

Front Sight is Available in Optic Yellow or Optic Orange Colors.

Optic Yellow™ 
 Bright Light Low Light

Optic Yellow glows the brightest and absorbs the most light, giving shooters the brightest night sights on the market.

Front Sight Focus

Our mission is to drive focus to the front sight for fast and accurate defensive shooting. Our Big Dots measure 0.188” (4.8 mm) wide, making them the biggest front sight on the market. The increased surface area makes the dot brighter in daylight and low-light.

Our express sight system is built for fast front sight acquisition, but they also help with eyesight issues. As we age, our eyesight degrades; our Big Dot is 50% larger than most conventional sights, which reduces strain on the eyes. The combination of a big front sight, open rear, and in-line sight alignment can help overcome cross-eye dominance, near or farsighted vision, and cataracts.

All XS night sights are CNC machined from steel bar stock in the great state of Texas.

The steel construction ensures the sights are protected from drops, racking off barricades, and will hold up for years. The steel surface is blued to resist rusting, with a regular cleaning and oil schedule. Big Dots are chemically resistant to acetone-based cleaning solutions and ultrasonic cleaners. The convex dot is gun powder residue resistant and can be easily wiped off with a cleaning cloth.

DXT2 Big Dots have no sharp edges and will not get caught on clothing when drawing the pistol from concealment. While Big, front sight still fits in most holsters.


Our express sights are designed to be installed with the file to fit method. You can find our videos demonstrating this method on our installation page or our YouTube channel. Sight pusher tools can damage our sights, as they are oversized to compensate for dovetail variance (It is better to be too tight vs. too lose). We supply all specialty tools in our packaging, including a Glock front sight screwdriver and thread locker.

We at XS, are shooters and machinist. We encourage you to try installing your own sights. If you run into any issues, we have you covered. Our customer service staff can walk you through the install, and our No-Questions-Asked Warranty policy covers our sights. If something goes wrong, we will get you a replacement and get your gun ready for duty.

With over 20 years of night sight manufacturing experience, we have learned that gunfights don’t happen in perfect light or complete darkness. They happen in between these two broad spectrums. Night sights don’t just need to glow in the dark. They need to be visible at all times.

During defensive altercations, you may experience an adrenaline rush that will cause your basic motor functions to become clumsy, fixated tunnel vision on the threat, and most likely both you and your attacker will be moving. Combat accuracy is crucial at this point, but people tend to not look at their sights when shooting in this situation (this is not point shooting). Our express sights ensure the big, colored, glowing front sight will be in your line of sight for a combat accurate sight picture that allows for a simple, sufficient alignment when there is insufficient time and distance between yourself and the threat.

All XS Sights products are protected by our No Questions Asked Promise. We will replace the product if it becomes damaged in any way or if the tritium stops glowing prior to 10 years.
