Express Big Dot Tritium Night Sights - Walther

Big Dot Express Sights

All our Big Dot Express sight systems offer a large and easy-to-see front sight. 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 Big Dot Express sights was to make them large and highly visible, addressing common issues such as aging eyes and deteriorating vision. The rear sight features a shallow V shape, ensuring a simple, low-profile design that offers a superior 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 line 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. Big Dot Express sights address these challenges by being big, bright, and easy to see, regardless of the scenario or time of day.

DXT2 PRO Walther PDP Sights Overview

Our DXT2 PRO tritium sights are optimized for self-defense situations. Our Big Dot front sight with tritium and photoluminescent glow dot ensures optimal visibility in bright or low light conditions. The bright Green color offers a high contrast front sight in daylight and glows brightly in low light. The Black Nitride surface finish gives enhanced corrosion resistance, making the set ideal for EDC in a sweaty or humid environment.

DXT2 Walther PDP Sights Overview

Our DXT2 tritium sights improved on our original flagship product. The front sight features a yellow or orange photoluminescent glow dot surrounding a tritium vial in the center. The combination gives you a vibrant front sight in bright light and a glowing sight in low light. The shallow V rear sight has a vertical tritium vial for low light indexing and is low profile to help draw your eye to the front sight.

DXW2 Walther PDP Sights Overview

Our DXW2 sights offer a simple dot-the-i sight picture with a reflective white stripe in the non-tritium rear. The front sight is equipped with tritium in the center, surrounded by our glow dot technology. The glow dot is photoluminescent, so it absorbs ambient light to provide a gentle glow in low light conditions. The yellow front glows the best in low light. Our orange front offers the most contrast in bright light but does not glow as brightly in low light.
