Sig P320 X-Compact Optics Ready 9mm Pistol with XRAY3 Night Sights

The Sig Sauer P320 X-Compact Optics Ready 9mm pistol brings Sig's modular platform into a carry-friendly package built for shooters who want duty-grade capability in a compact frame. This is a serious defensive or range pistol that doesn't compromise on features—the optics-ready slide accepts popular compact red-dot sights, the X-Compact grip module is shaped for control and speed, and the flat-trigger design breaks clean. It ships with two 15-round steel magazines and XRAY3 night sights that work in daylight and dark, so you're ready to train or carry the moment it arrives.

What sets this X-Compact apart from generic compact 9mms is the ergonomic engineering: the beavertail is extended and undercut to tuck high in your hand and reduce hammer bite, the magwell is funnel-shaped for faster reloads, and the trigger itself is the upgraded XSeries flat design that Sig builds into their higher-end models. Stainless steel slide and frame resist corrosion, and the Nitron finish is tough against wear. At 3.6 inches of barrel and 7 inches overall, it's short enough for concealed carry but long enough to keep sight radius useful—5.5 inches of sight line is solid for a compact. Weight comes in at 25.3 ounces loaded, which is reasonable for the round count you're carrying.

Whether you're building a duty gun, a backup, or a personal-defense pistol you actually want to shoot regularly, the P320 X-Compact Optics Ready gives you flexibility. Run it with factory night sights, swap in your preferred red dot, or do both—the modular design is the whole point. Sig's P320 platform is proven in the field, and this version turns down the size without turning down the capability.

Frequently Asked Questions

What red-dot sights will fit the optics-ready slide?

The slide is cut for Romeo1PRO, Delta Point Pro, and RMR footprints, so any red dot designed for one of those platforms will mount directly. The gun also functions perfectly with the included XRAY3 night sights if you prefer iron-sight shooting or want to run irons as backup.

Is this P320 X-Compact good for concealed carry?

Yes. At 3.6 inches of barrel and 7 inches overall length, it's designed as a compact carry gun. The width is 1.3 inches, and it weighs 25.3 ounces loaded—proportions that work well for inside-waistband or appendix carry. Sig built the beavertail and undercut trigger guard specifically to make it comfortable and fast-drawing for daily carry.

What comes in the box?

You get the pistol, two 15-round steel magazines, and the XRAY3 night sights already installed. It's a complete firearm ready to shoot or carry—no additional sights or magazines needed out of the box.

Can I swap the grip module to a different size?

The P320 platform's modular design allows grip-module changes, but we can only speak to what this specific model ships with: the XSeries Compact Medium grip. For questions about module compatibility or upgrades, contact us or consult Sig Sauer directly.
