The SIG Sauer P320-XCARRY is a modular, optics-ready striker-fired pistol built for serious concealed carry and duty use. It combines SIG’s proven P320 FCU with an enhanced X-Series grip module and slide for superior control. Since we started stocking it in Q4 2025, it’s become a steady seller for good reason. The finish quality on our batch is excellent, with no visible tooling marks.
Key Features
- Modular FCU: The serialized Fire Control Unit is the firearm, allowing you to swap grip modules and slides for a custom fit without an FFL transfer.
- Optics-Ready Slide: The slide is cut from the factory to accept SIG’s ROMEO1PRO and other popular micro red dot sights.
- X-Series Grip: Aggressive texturing and an undercut trigger guard provide a high, consistent grip for enhanced recoil management.
- Flat X-Series Trigger: Delivers a crisp, consistent break with a short, tactile reset for faster follow-up shots.
- Enhanced Sights: Features SIG’s X-RAY3 Day/Night front sight paired with a serrated rear sight that co-witnesses with an installed optic.

Frequently Asked Questions
Is this the same as the military’s M17/M18?
The P320 platform is the basis for the U.S. military’s M17 and M18 service pistols. The XCARRY variant is a commercial model with the enhanced X-Series grip module, flat trigger, and optics-ready slide, offering more modern ergonomics and features than the standard-issue configuration.
What optics fit the slide cut?
The slide is cut for the SIG Sauer ROMEO1PRO footprint. Adapter plates from SIG and other manufacturers are readily available to mount other popular micro dots like the Trijicon RMR, Holosun 507C, and Leupold DeltaPoint Pro.
Can I change the grip size?
Yes. The modular design allows you to purchase different sized P320 X-Series grip modules (Small, Medium, Large) separately and install your FCU in minutes with no tools required, customizing the fit to your hand.
