Big Dot and Standard 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, while green is an excellent option for low light and has a very bright glow intensity. XS Tritium Night sights are big, bright, and easy to see day or night!

The sights are CNC machined from solid steel bar stock by our in-house machine shop. We design, machine, and insert our tritium to produce the highest quality possible and provide American Made products.

We are a small, second-generation family-owned business based in Fort Worth, TX, and our customers are family. We live, eat, and breathe guns. We offer easy DIY install instructions and a 30-Day Satisfaction Guarantee. If you have color vision issues and can't see the front dot, call us, and we will get another color shipped out - over 5% of the population has color blindness to a degree!

    I have installed XS sights on most of my carry and backup wheelguns and autos. They really help old eyes!

    Standard dot for S&W Jframe

    Posted by Shaun Herdegen on Oct 20th 2022

    This is not my first time using XS I have them on many pistols and this one is on a S&W snubby . I find that they are very easy to pick up in all lighting . I have put them on both my daughters pistols and they said XS sights make shooting much easier though my girls are Cracker Jack shots anyway . James Yeager introduced me to them on his YouTube channel and he was passionate about these and he was right to be so !
