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 instructions, a 30-Day Satisfaction Guarantee, and stand behind a 10-Year No Questions Asked Warranty on all our sights. If you break your sight training, we want to hear about it. If you damage your sight installing it, give us a call, and we will get a new one mailed out after a friendly lecture from one of our gunsmiths. 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!) Either way, our products are built to take a beating, and we have your back if anything happens.

    orange Big Dot tritium

    Posted by old guy on Jun 19th 2022

    Great front sight. Very hard to install: base steel too hard, broke off 2 bits trying to drill base. Done 3 of these before and that never happened. Very difficult to drive out broken tips of bits.

    SP101 Big Dot

    Started out with the white Big Dot on my SP101, loved it! That is, until I had to replace it due to breaking it, and now I am even more impressed with the green Big Dot on the 101!!! The color difference is very eye grabbing for me, and the dark visibility is second to none. Thanks to XS for a premium product, and standing behind their product with a premium warranty!!!
