SIG Sauer P320 XCarry Pro X-Series “Agency Vault” 9mm — Limited Law-Enforcement Allocation
This as-new SIG Sauer P320 XCarry Pro comes from the Agency Vault law-enforcement program, a small-batch allocation normally reserved for police and government contracts and only rarely released to civilian buyers. Built on the modular P320 platform, it pairs a 3.9-inch stainless steel barrel with the enhanced X-Series grip and a PRO-cut slide that is optics-ready out of the box. Its flat-faced trigger, suppressor-height X-RAY3 tritium sights, and ambidextrous controls make it a standout carry or duty sidearm.

Produced in SIG’s Newington, New Hampshire facility, this Agency Vault variant is classified as rare and was originally earmarked for law-enforcement distribution, identified by its model number W320CA-9-BXR3-PRO-AEU. Civilian availability is limited to aftermarket channels, giving this example strong collector appeal along with practical performance.
The serialized fire-control unit—the heart of the P320 system—allows caliber and frame-size conversions, letting the owner adapt the pistol to different roles without additional paperwork. Its striker-fired action provides a consistent trigger pull, and the flat-faced X-Series trigger promotes a straight-back press for enhanced control.
The wrap-around textured X-Series grip module offers a high undercut beavertail and extended trigger-guard undercut for a secure, high grip. Ambidextrous slide-catch levers support left- or right-handed operation, while the four-slot MIL-STD-1913 rail accommodates weapon-mounted lights or lasers.
The Black Nitron slide features deep forward and rear cocking serrations plus a PRO optics cut compatible with SIG ROMEO1PRO and Leupold DeltaPoint Pro footprints. Suppressor-height X-RAY3 tritium sights provide a bright day/night sight picture and co-witness through most mini-red-dot optics.
