SIG Sauer P320 X-Series XCarry Pro 9mm 3.9" LE Agency Vault — Modular, Optics-Ready, Night Sights, 17+1
This P320 XCarry Pro comes from SIG Sauer’s limited Law Enforcement Agency Vault allocation, making civilian examples scarce and highly collectible. Built on the proven modular P320 platform, it combines a full-size X-Series grip module with a compact 3.9-inch stainless barrel, factory XRAY3 night sights, and a PRO-cut optics-ready slide — all in as-new condition.

What’s Included

Released primarily to police and government agencies, the XCarry Pro was produced under SKU W320CA-9-BXR3-PRO and distributed to civilians only in small aftermarket overruns, underscored by its 58J serial prefix.
The modular, removable fire-control unit (the serialized chassis) allows caliber and frame changes without additional FFL transfers, supporting the P320’s reputation for adaptability.
A flat-faced trigger with a short, tactile reset teams with striker block and disconnect safeties for a responsive yet secure firing sequence, while the reversible magazine release accommodates left- or right-handed shooters.
The matte-black slide wears forward and rear serrations plus SIG’s PRO optics footprint, ready for direct mounting of ROMEO-X/PRO, Leupold DPP, and other compatible sights. Factory XRAY3 tritium front and rear sights provide a bright day-night sight picture if you prefer irons.
A MIL-STD-1913 accessory rail, full-size 17-round grip, and three included magazines round out a duty-ready package that remains uncommon on the commercial market.
