The SIG Sauer X-Ray3 Day/Night Sight Set drops a #8 green front and a #6 square-notch rear onto your SIG for a sight picture that works around the clock. The idea here is simple: a big, high-contrast green ring up front against a clean blacked-out rear pulls your eye straight to the front sight, which is exactly where it needs to be when you're lining up a shot. During the day that oversized fluorescent front dot jumps out at you, and when the light drops the 3-dot tritium takes over with its own self-powered glow.
This particular set runs a taller #8 front paired with a lower #6 rear in a square notch, which is one of SIG's more popular carry and duty pairings. The tritium is genuinely self-illuminating, so there's nothing to charge and nothing to switch out between day and night use. With a tritium half-life around 12 years, these keep glowing bright for over a decade of everyday carry, range time, or duty rotation.
SIG wraps steel around the tritium vials, which shields them from recoil, cleaning solvents, and whatever the weather throws at them. The company torture-tested the design to 20,000 rounds, so this isn't a set that's going to shake loose or dim out on you early. That steel housing is a big part of why the X-Ray3 comes standard on SIG's Legion series pistols.
The X-Ray3 set fits a broad lineup including the P320, P938, P238, P229, P226, P220, P227, and P225. Both front and rear are dovetail mounted, and getting them seated correctly really calls for a proper sight pusher rather than a punch and hammer. If you're matching what's already on your slide, check the small number stamped on your current sights and pick the same combination so your point of impact stays true.
This set is built to fit a wide range of SIG models including the P320, P938, P238, P229, P226, P220, P227, and P225. If you're unsure, check the small size number stamped on your existing front and rear sights. Matching that number combination keeps your point of impact consistent after the swap.
No batteries required. The X-Ray3 uses a self-powered 3-dot tritium system that glows on its own in low light. With a tritium half-life of around 12 years, you get more than a decade of reliable nighttime illumination.
Both the front and rear are dovetail mounted, and they seat best with a proper sight pusher rather than a hammer and punch. A pusher lets you center them cleanly without marring the sight or slide. Many folks with the right tools do it at home, but a gunsmith can handle it quickly if you'd rather not risk it.
The #8/#6 pairing gives you a taller front and lower rear, which is a common carry and duty setup on many SIG pistols. The tall, high-contrast green front is easy to pick up fast, especially against the blacked-out rear. If your current sights are a different combination, match the numbers so your zero holds.
