The Sig Sauer P320 X-Series in 10mm is a serious duty and defense pistol built for shooters who want a modern, modular platform with genuine stopping power. This optic-ready configuration pairs the proven P320 fire control unit with Sig's full-size X-Series grip module, a 5-inch bull barrel, and a slide milled for red dot mounting—making it equally at home on the range, in tactical training, or as a deep-carry defensive option. The 10mm cartridge delivers rifle-grade terminal performance from a handgun form factor, and this X-Series build adds refined ergonomics, a flat trigger with crisp break, and tritium-illuminated sights that work day or night.
What sets the X-Series apart is attention to detail in the human interface: the flat trigger breaks cleanly at 90 degrees, the grip texturing is aggressive without being punishing, and the full-size module gives you real estate for a solid two-hand purchase. The manual safety is standard here, giving operators a third point of control. The stainless steel slide wears Sig's proven Nitron finish for corrosion resistance, and the slide is already cut for SIG LOC-compatible optic footprints, so adding your preferred red dot is straightforward. Two 15-round steel magazines come in the box, giving you serious capacity for a 10mm gun.
This is a handgun for the shooter who understands ballistics and doesn't need marketing hype—just honest capability. Whether you're preparing for backcountry defense, serious pistol work on the range, or simply want a 10mm that doesn't feel like you're wrestling a brick, the P320 X-Series delivers. It's modular (you can swap grip modules and fire control units), it's reliable, and it points naturally out of the box.

| Overall Length | 8.5 inches |
| Overall Height | 5.6 inches |
| Overall Width | 1.4 inches |
| Sight Radius | 6.8 inches |
| Weight (with magazine) | 33 ounces |
| Slide Material | Stainless Steel (Nitron finish) |
| Frame Material | Stainless Steel |
| Grip Module | Polymer X-Series, full-size |
| Sights | XRAY3 day/night tritium |
| Trigger | Flat, striker-fired, 90-degree break |
| Magazine Capacity | 15 rounds |
| Magazines Included | 2 steel magazines |
| Safety | Manual safety |
Yes. The slide is milled and ready for SIG LOC-compatible red dot optics. You won't need a separate mount—just install your sight directly into the slide cut.
This model includes a manual safety equipped fire control unit, giving you an extra layer of control. Other P320 configurations may use strikers without a manual safety. The choice depends on your training, carry method, and personal preference.
Both rounds are available in the X-Series platform. This pistol is chambered in 10mm, which delivers higher velocity and flatter trajectory than .45 Auto. The 10mm is favored by shooters prioritizing velocity and range performance; .45 Auto offers slightly softer recoil and wider ammunition availability. Your choice depends on your intended use and ammunition accessibility in your area.
The P320 X-Series 10mm ships with XRAY3 day/night tritium sights, which glow in low light and remain visible in bright conditions—a practical choice for any serious use.
