Xs Sight Dxt2 Big Dot For Sig P239 - Yellow

The XS Sights DXT2 Big Dot night sight set for Sig P239 brings reliable low-light performance to a compact, carry-ready pistol. Built for shooters who trust their P239 for personal defense and need sights that work when the sun goes down, this tritium-powered front sight pairs a high-contrast yellow glow dot with a rear sight that features both tritium and a white outline. The result is a sight picture that's fast to pick up in darkness and easy to index in daylight — no fiddling, no learning curve.

The front sight's big dot design (0.188" diameter) gives you a simple, instinctive aiming reference. That yellow-colored glow dot absorbs ambient light and glows in low-light conditions, so you're never relying on battery power or electronic gadgets. The low-profile V-shaped rear sight keeps your attention on the large, bright front dot while still providing enough mass for reliable sight acquisition. A tritium-filled center in the rear sight backup ensures visibility in complete darkness.

Built from durable CNC machined steel, these sights are made to last. The rear sight ledge lets you manipulate the slide one-handed if needed — a practical detail for defensive shooters. Because this is a tight-tolerance sight set designed specifically for the P239 platform, fit and function are direct and reliable. Standard holsters remain compatible, so you don't need to overhaul your carry setup.

The rear sight ledge allows you to manipulate the slide with one hand — a practical feature for defensive shooting scenarios where your strong hand may be occupied.
