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!

Yellow Big Dot on Model 360
Fitted my new yellow, big dot front sight on my S&W model 360 over the weekend. Had basically no issues, except I snapped one drill bit, I'd bought a dozen 1/16" bits and a package of 1/16" Stainless Steel roll pins on amazon before I started so I'd be prepared. I was a little concerned that the new sight wouldn't cover the entire sight channel, but that wasn't an issue on my gun either. Personally, I couldn't be more pleased, it looks and works great. This is the perfect front sight for a j-frame!

Big Dot S&W revolver front sight
I love your BIG DOT front sights. I run them on four of my revolvers and three 1911's. With old eyes, I can still see the front sights. They are a great help. THANKS !!
I put a white BIG DOT front sight on my S&W 360 retirement gun. The sight is simply fantastic! I’ve got glaucoma and cataracts started in my retired cop eyes and the one sight i can ONLY really pick up is my BIG DOT XS Sight. I’m extremely impressed and highly recommend this site.
I am able to get on target faster and can keep both eyes open better.
Big Dot on S&W 340PD
Installed very easily in 15 minutes with #54 cobalt drill bit and 1/6 x 1/4 roll pin. Was concerned that the big dot would overwhelm the little J frame, but it worked out well. Either big dot or regular dot will more than satisfy most shooters.
I really like the sight
It was a big improvement, and I would recommend it.
