Big Dot Night Sights are defensive tritium sights designed to enhance your defense gun. The sights use 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. Designed to be large and highly visible, these sights help 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 white dot does not glow but is reflective, so it is an excellent option for bright and low light. XS Tritium Night sights are big, bright, and easy to see day or night!

Easily upgrade your Smith and Wesson pinned revolver ramp sight with a precise sight picture! Our front sights are a superior upgrade over factory ramp sights. The sight acquisition is faster, and alignment is more repeatable than ramp sights. See your sights in low light! Whether you're rocking your wheel gun for EDC, as a backup gun, or as a nightstand gun, you need to see your sights in the dark. Our photoluminescent and tritium front sights are the brightest low-light option on the market. Improve your accuracy with a precision sight picture. Ramp sights make precision shots difficult because setting the elevation repeatedly and quickly is hard. Our dot front sights make shooting easy. Simply put the bottom of the dot in the channel and cover the spot on the target you want to hit with the whole sight.
