Don't Struggle to See Your Front Sight!

DXT Night Sights are defensive tritium sights designed to enhance your EDC pistol. The front sight uses a reflective white dot that bounces ambient light for increased low light visibility. We designed the DXT sights to be large and highly visible; this helps solve many issues, from aging eyes to deteriorating vision. 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. DXT Night sights are big, bright, and easy to see day or night!

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. Either way, our products are built to take a beating, and we have your back if anything happens.

    Great sites - Repeat customer

    Posted by BartLanz on Dec 1st 2022

    I purchased the standard version of these in 2018 after the recommendation made by James Yeager. I have been shooting them and using them for 4 years now and have no regrets, the sites are great, allow for easy and fast acquisition in all lighting scenarios. I am now outfitting a G19 with a red dot, and after looking at other sites, I have decided to "come home" to that which has worked well for me and got the suppressor height sites for this one.

    Big dot Suppressor height sights

    Posted by Eric Nygaard on Sep 1st 2022

    My second set of XS sights I got. This set I had to do a little more filing than I thought I would have to do. Other than that it was an easy install again. Love how they co-witness my slide red dot. They are so much easier to pick up than factory Glock sites. Should have got these years ago!!
