XS Sights Big Dot Tritium Night Sight Set – S&W J-Frame / Ruger SP101

The XS Sights Big Dot Tritium night sight set delivers fast target acquisition in low-light conditions with a single, oversized tritium front dot. Designed for defensive revolvers, the Big Dot front sight uses a high-contrast green tritium insert that draws the eye instantly in reduced lighting, while the shallow V rear notch provides rapid sight alignment at close range. This configuration prioritizes speed over precision—ideal for self-defense scenarios where getting on target quickly matters most.

Machined for drop-in installation on Smith & Wesson J-Frame revolvers and Ruger SP101 models, this sight set is built from steel with a durable finish. The oversized front dot measures larger than standard tritium inserts for maximum visibility, and the tritium is self-illuminating for up to 12 years. No batteries, no switches—just reliable night sights when you need them.
