SIG Sauer P320 Pro Full-Size X-Series 9mm Law Enforcement Agency-Vault Optics-Ready
This P320 Pro Full-Size X-Series comes directly from SIG Sauer’s limited Law Enforcement allocation, built in the Agency Vault for police and government contracts and seldom released to civilian channels. It ships in virtually new condition, offering a modular stainless-steel chassis, optics-ready Pro-cut slide, and flat X-Series trigger—all factory features that mirror the lineage of the U.S. M17/M18 service pistols.

The modular, serialized stainless-steel Fire Control Unit is the heart of the P320 system, allowing caliber and frame swaps without the need for an FFL transfer—flexibility highly valued by professional users.
Its 4.7-inch nitrided stainless barrel pairs with a matte black Nitron slide that sports deep front and rear serrations for confident manipulation in any condition.
The slide is factory-milled for the DeltaPoint PRO/Romeo footprint, giving the buyer a direct mount solution for modern duty-grade optics.
SIG’s flat-faced, skeletonized X-Series trigger shortens reach and delivers a crisp break, while the reversible magazine release supports both right- and left-handed shooters.
XRAY3 day/night sights—a green-ring front blade and serrated rear notch—provide 24-hour visibility, rounding out a package purpose-built for professional performance.
