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 install instructions and a 30-Day Satisfaction Guarantee. 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!

    DXT2 Big Dot Night Sights

    Posted by James Hink on Sep 9th 2023

    I am not a professional shooter but after purchasing and installing the DXT2 Big Dot Night Sights and after numerous range trials I have found that these sights greatly assist in quick aim acquisition and putting rounds on target with in what is considered "self defense" distance...I give this product a thumbs up.

    DXT2 on CZ75D PCR

    Posted by Dave in SE Texas on Jun 10th 2023

    CZ front sights are low and narrow, which don't work well with my middle aged eyesight. I've tried the original CZ glow sights, tritium front, and fiber optic front. All being no taller or wider than the original CZ size. The DXT2 set of sights that are now on my CZ PCR are larger and taller. Much easier for my eyes to pick up. I'd say these sights are the best thing short of going to a red dot. And the DXT2s are much lower profile than a red dot, so no holster changes needed. It only took me one 50 round box of ammo to figure out how to use the gun with the DXT2. Cover your target with the big dot and pull that trigger.

    Best I've tried

    Posted by Tucker Kelsey on Mar 13th 2023

    I love these sights! Bought a pair for my P-07 then had to have another set for my P-09! I also like how these install easily with the two set screws on the rear sight. Very easy to drift but still secure.

    DXT2 Big Dot Yelllow with Tritium rear - CZ P07

    Posted by M.R. on Feb 1st 2023

    Very happy with these sights. Compared to the stock tritium 3 dot setup on this P07 Tactical, the XS sights are much more intuitive to pickup the front sight with in any light condition. Simple to install as well after you review the installation videos available. Give these a try and you wont be disappointed.

    DXT2 Yellow Big Dot

    Posted by Dale Fate on Jul 13th 2022

    It’s simply the best night sight available. I’ve installed DXT2 Yellow Big Dot’s on both CZ-PCR and Glock 26. They’re very visible both day and night. You can quickly and easily align the front and rear sights on target. XS also has the best customer service.

    DXT2 Big Dot Night Sights

    Posted by Wes Howe on Jun 1st 2022

    I purchased the subject sights because I liked the way they "pull" your eye to the front sight. The sights were installed by my local Gun Smith named Guncrafters. After initial sight in/installation I couldn't be happier with the product. The DXT2 Big Dot Night Sights are recommended without reservation Wes Howe Salem, OR

    Quick 'n' Bright Night Sights

    Posted by Rick J on Mar 3rd 2022

    In any lighting condition I find the XS Big Dot with tritium inserts is much quicker to line up than the oe CZ97B setup. Sunshine, dusk, or a dark room, these sights really stand out. This product exceeded my expectations by far, thanks XS!
