XS Standard Dot Tritium Front Night Sight for S&W J Frame & Ruger SP101 - White

The XS Standard Dot Tritium Front Night Sight for S&W J Frame and Ruger SP101 is a defensive handgun sight built for shooters who need reliable target acquisition in any lighting condition. Machined in Fort Worth, Texas, this tritium night sight pairs a green tritium element with a white dot outline, giving you both low-light capability and strong daytime visibility. The Standard Dot design—larger than typical front sights for faster acquisition under stress, yet smaller than a Big Dot to keep your sight picture uncluttered—works across daylight, twilight, and complete darkness. Simply align the bottom of the dot in the bottom of your sight channel and center it on your target within 15 yards. Whether you carry a S&W J-Frame revolver or a Ruger SP101, this pinned front sight is precision-engineered to fit your platform and stay put through thousands of rounds.

XS Sights sights are designed by shooters for shooters, and this Standard Dot is no exception. The white outline reflects ambient light, so even in moderate low-light scenarios you get visual feedback without relying solely on tritium glow. The 0.140" outside diameter is slim enough to fit common holsters without modification, meaning you can upgrade your night sight without a gear overhaul. Installation does require a drill press to set the retaining pin hole, so plan accordingly or have a gunsmith handle it.

If you rely on your revolver for defense or duty carry, night sights aren't a luxury—they're a fundamental upgrade. This XS Standard Dot gives you the speed and confidence to shoot accurately when light is low, and the daylight performance to keep your groups tight at the range. It's a straightforward, proven solution for shooters who demand more from their iron sights.
