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.

    Installed sights on spouse's M&P Shield EZ

    Posted by Ride The Heights on Feb 23rd 2023

    Front sight took some tapping with an old flat nose screwdriver to release the E clip. Once removed, easy install of XS front sight. Rear sight easy removal & install of new sight. I've have these DXT2 on my CCW also. Quick front sight acquisition with orange post. Challenging friends on a dueling tree using this sight leaves me smiling, & they confused.

    Fast sights , quality product. I use on revolvers and semi autos alike. The fit on S&W autos may require fitment of front sight. Check the rear sight from both sides before fitment .

    DWT2 sights

    Posted by Kevin Bonebright on May 21st 2022

    I purchased the DWT2 sights for my EDC a M&P Shield 9EZ, they are bright enough that there is never a time in bright light to the blackest night that I feel confident enough to pull the trigger knowing I’m going to hit my mark if and when self defense is needed, I hit the front sight with a flash of my high powered flashlight no more than a second of light hits it and it will illuminate the big dot front so I can see it even with no glasses on in the dark of night and allow me to hit my target, and my sight is blurred without my glasses on, this is truly a quality product that I recommend! Easy to install, you can use their video instructions on the website and do it yourself if you have a bit of mechanical skill, the staff knows their products when you give them a call and they have a excellent warranty and care about customers satisfaction, that something you don’t get much anymore!

    Smith and Wesson DXT2 Big Dots

    Posted by Nick on Jan 12th 2022

    If you’ve taken the time to read the review, just go ahead and buy the sights. I bought these as a gift for my father in law, and have a set of them on my Glock 17 that I have carried daily for the past 7 years. They are fast to acquire and plenty accurate if you are doing your part behind the gun. As an Added bonus, XS’s customer service is by far THE best you will ever deal with if you have a problem.
