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.

    Sight set

    Posted by Chad on Nov 9th 2022

    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.

    Best for where gun fights happen

    Posted by Drew on Aug 24th 2022

    I've been a Big Dot user for over 15 years. Having used them in Force on Force and thousands of hours of practice. Big Dots are the best sight for the distances where actual gun fights happen. Worried about long range? Take them out to the range and join the long list of shooters who have used them to hit a pepper popper at 100 yards. Finally, the DXT2 is the next step in the evolution with the glow in the dark paint that makes them unmistakeable in low light.

    Excellent product, Amazing customer service!

    Posted by Dale Fate on Jul 13th 2022

    I’d purchased the DXT2 Yellow Big Dot sights for my CZ….I loved them so much that I ordered another set for my Glock. I followed the XS installation video which made the fitting very simple. Later that evening I realized the rear sight on the Glock was noticeably dimmer than that of the CZ. After several failed attempts to get a reply by email, I eventually called XS. The customer service agent was understanding to my expectations and offered to send a replacement rear sight. Thank you XS for your excellent customer service. I recommend calling XS instead of emailing….you’ll get a much quicker reply!
