DXW2 Big Dot Night Sights - Walther

Big Dot Express Sights

All our Big Dot Express sight systems feature a large, easy-to-see front sight. The front sight uses a unique photoluminescent Glow Dot that absorbs surrounding light and emits a gentle glow in low light. The dot's convex shape provides a larger surface area, maximizing light absorption and intensifying the Glow Dot's brightness. 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 in any scenario or time of day.

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.
