Don't Struggle to See Your Front Sight!

Our DXT2 Night Sights for Glock are tritium night sights specifically crafted to enhance the performance of your EDC pistol. These defensive sights are meticulously designed with features to ensure optimal visibility in low-light conditions. The front sight utilizes a unique photoluminescent Glow Dot, which absorbs surrounding light and emits a gentle glow when lighting is limited. The convex shape of the dot provides a larger surface area, maximizing light absorption and intensifying the brightness of the Glow Dot. Our primary objective when designing the DXT2 sights was to make them large and highly visible, addressing common issues such as aging eyes and deteriorating vision. During our testing, we observed that the orange front sight is most visible in daylight, while the yellow variant glows brighter in low-light environments. The rear sight features a shallow V shape, ensuring a simple, low-profile design that offers an extensive field of view.

To prevent confusion between the front and rear sights in high-stress situations, we adopted the "dot-the-i" sight picture. This sight picture consists of a tritium dot in the front sight and a tritium bar in the rear sight, facilitating quick and accurate target acquisition. In most gunfights, both the victim and attacker are in motion, with the victim primarily focused on the threat. The DXT2 Night Sights address these challenges by being big, bright, and easy to see, regardless of the time of day.

XS DXT2 Tritium Night Sights serve as exceptional defensive sight choices for your pistol, ensuring the front sight remains visible regardless of lighting conditions. With these sights, you will be prepared for any potential confrontation, regardless of the lighting conditions you’re in.

    DXT2 Big Dot Night Sights - Glock 26 & 20

    Posted by Dennis on Aug 27th 2023

    Having used XS Big Dot night sights on a Glock 17 for competitions for nearly 15 years, I had learned to appreciate the rapid target acquisitions that the Big Dot sights afforded me. I decided to install the XS DXT2 Big Dot night sights with an orange front sight on a Glock 26 for carry purposes, I was plesantly surprised how quickly the orange front sight enabled me to get on target. Prior to installing the Big Dot night sights I was concerned that I was potentially sacrificing accuracy due to the size of the Big Dot front sight on a Glock 26 However, after few trips to the range I realized that I could still easily hit a 2" x 2" targer area repeatedly at 10 years. I liked it so much that I installed the sights on a Glock 20 as well. I have shot approximately 750 rounds through my Glock 26 with the Big Dot night sights and the sights have not loosened. I would highly recommend these sights!

    First choice in word and in deed, pictures do no justice. Just recieved and installed these sights on my 30 year old Glock 21, replacing weekend adjustable sights. Machine work is outstanding. Materials are outstanding. Sight picture is awesome. Installation was straight forward with special tools included. To my 50 year old eyes, Sublime. Thank you XS sights. May fortune smile upon you:)

    Definitely an upgrade

    Posted by Anonymous on Aug 5th 2023

    I enjoy the sight picture of this sight much more than typical notch and post sights. It is a bit of a learning curve but makes quick accusations of your sights much easier. I chose the orange color, which is very effective in the daylight as it contrasts a lot but is lacking in darker light conditions so you become much more reliant on the tritium insert. Will go with the yellow color from this point on when I buy new sets of this sight. Definitely now my go to pistol iron sights.

    New sights

    Got six new sights for multiple Glocks and the rear sight install tool worked the best. Amazing how fast my eyes catch the front sight. James Yeager was right
