XS Sights
The XS Sights DXT2 Big Dot night sights for Sig Sauer are purpose-built for shooters who need reliable low-light target acquisition without batteries or electronics. The standout feature is the large, high-contrast green tritium front sight with a yellow outline—a combination that bridges the gap between fast daylight shooting and confident night work. The 0.188" diameter front dot is big enough to find quickly but precise enough for accurate shot placement, while the simple dot-the-"i" sight picture (dot centered on the rear notch) is intuitive under pressure. Whether you're carrying a Sig for personal defense, running low-light drills at the range, or shooting in variable light conditions, these sights give you a fighting tool that works when your eyes are adjusting or when conventional sight pictures aren't reliable.
The rear sight's low-profile V-notch keeps the focus on that glowing front dot and gives you better sight visibility overall. The white stripe on the rear is non-tritium, so you're not paying for unnecessary glow where you don't need it. The ledge machined into the rear sight is a practical detail—it's there if you ever need to manipulate the slide one-handed. Everything is CNC machined steel, built to take the abuse of carry, training, and competition without fading or coming loose.
XS Sights designed these sights to fit standard Sig Sauer holsters, so you're not buying a dedicated holster just to accommodate the hardware. The green tritium and yellow outline front sight is a proven combination for fast acquisition in low light while remaining sharp and usable in daylight. If you want night sights that are ready to go out of the box and don't require aftermarket gunsmithing, the DXT2 delivers straightforward, functional low-light aiming.
