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 ambient light and emits a gentle glow in low-light conditions. 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 low-profile design with 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 features a tritium dot in the front sight and a line in the rear sight, enabling quick, 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 Glock 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 both bright and low-light conditions. The bright Green color provides a high-contrast front sight in daylight and glows in low light. The Black Nitride surface finish provides enhanced corrosion resistance, making the set ideal for EDC in sweaty or humid environments.
DXT2 Glock Sights Overview
Our DXT2 tritium sights are an improvement over 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 features a vertical tritium vial for low-light indexing and a low-profile design that draws your eye to the front sight.
DXW2 Glock 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 a tritium center dot, surrounded by our glow dot technology. The glow dot is photoluminescent, absorbing 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.
