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!

Also available with a non-tritium rear sight for those who prefer only one glowing index point and a more budget-friendly option. DXW2 Night Sights also feature a dot-the "i" sight picture, but with a white stripe non-tritium rear and a tritium front sight. The front sight offers the same excellent Glow Dot and tritium visibility. The simplistic rear and reflective white stripe provide a visible alignment point while reducing focus on the rear and driving attention to the front sight.

XS DXT2 and DXW2 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.

    So target. Much comfort.

    After using some XS sights in a training class, I replaced a set of night fision sights with these on my Glock 19. Now the only thing I’m not looking forward to is having to buy close to a dozen new pairs of big dots.

    DXT2 Night Sights

    Posted by Mark Villalon on Dec 31st 2022

    For my Glock 43 this sight picture with the orange is excellent for my EDC for close quarters. Being the dot is very big it is easy to pick up the front sight and get on target quickly. I am not sure for distance targets, but for 15 feet or less they are outstanding for me and the purpose I carry. I recommend them.

    Front site is wonderful. Rear sight does not work with my macular degeneration. I much prefer the notched F8 rear site.

    Sight set

    XS sights. Accept no substitute. They do great at range with steel targets at 15 yards. Fast acquisition. I have them on all my carry auto pistols.

    Nice sights

    Posted by Cordell on Sep 29th 2022

    Install was pretty easy. I had never installed sights before. It was quite a bit of filing on the rear. I haven’t had a chance to shoot yet, but they look awesome, and appear to pick up target quickly.
