Don't Struggle to See Your Front Sight!

DXT2 Night Sights are defensive tritium sights designed to enhance your EDC pistol. The front sight uses a proprietary photoluminescent Glow Dot that absorbs ambient light and glows in low light. The convex dot's additional surface area increases light absorption, intensifying the charge of the Glow Dot. We designed the DXT2 sights to be large and highly visible; this helps solve many issues, from aging eyes to deteriorating vision. We've found that the orange front tends to be most visible in daylight settings and that yellow glows brighter in low light. The shallow V rear has a simple, low profile that provides a wide field of view. The dot-the "i" sight picture, with a tritium dot in the front and a tritium bar in the rear, prevent confusing the front and rear sight in high-stress situations. In most gunfights, the victim and attacker are moving, and the victim is threat-focused. DXT2 Night sights are big, bright, and easy to see day or night!

XS DXT2 Tritium Night Sights are excellent defensive sight options for your pistol that will keep your front sight visible day or night. That way, you'll be ready for the fight, no matter the light.

The express sight concept started it all for us over 25 years ago. Our founders wanted to engineer a sighting system primed for defensive situations that was big and easy to see. Modeled after African big game hunting sights, express sights are designed to give you a visible, and combat accurate flash sight picture when seconds count.  

The sights are CNC machined from solid steel bar stock by our in-house machine shop. We design, machine, and insert our tritium to produce the highest quality possible and provide American Made products. We are a small, second-generation family-owned business based in Fort Worth, TX, and our customers are family. 

We live, eat, and breathe guns. We offer easy DIY instructions, a 30-Day Satisfaction Guarantee, and stand behind a 10-Year No Questions Asked Warranty on all our sights. If you break your sight training, we want to hear about it. If you damage your sight installing it, give us a call, and we will get a new one mailed out after a friendly lecture from one of our gunsmiths. If you have color vision issues and can't see the front dot, call us, and we will get another color shipped out. (Over 5% of the population has color blindness to a degree!) Either way, our products are built to take a beating, and we have your back if anything happens.

    Big Dot Night Sights

    Posted by Steve on Jul 20th 2022

    I ordered the Big Dot sights for my pistol, and had them installed. They worked great...for about 3 days. The big front sight glowed well the 1st night, dimmer the 2nd and dead the 3rd night. I contacted XS about the problem and they shipped a replacement sight out that same day. I replaced it with the new sight and weeks later it is still glowing bright. The sights and their customer service are both top notch.

    DXT2 Big dot for H&K USP

    Posted by Mike on Jan 12th 2022

    The front sight is perfect, the fit, the view and easy to put on target faster, the rear did not fit my gun. the dove tail was angled different, and the glow stick sat below the bridge, and you can only see the top end so i pulled it off and put the original back on and only use the front. The big dot on the front of the gun makes it very easy to see even when you look through the sight like i do when shooting. over they work on the front but not on the back it needs improvement on the dove tail and on the height.
