SIG Sauer P320 XCarry Pro X-Series “Agency Vault” 9mm, Compact, 17+1, Optics-Ready
This P320 XCarry Pro comes from SIG Sauer’s restricted Agency Vault program, normally reserved for law-enforcement contracts and rarely released on the commercial market. Built on the modular P320 platform, it blends compact dimensions with duty-grade features, including a cold-hammer-forged 3.9-inch barrel, XRAY3 tritium sights, and a factory-milled slide ready for PRO-footprint optics.

Issued through SIG’s law-enforcement allocation, this handgun represents one of the few Agency Vault examples to reach civilian hands. Collectors value the traceable provenance and limited availability, while shooters appreciate its fully vetted duty configuration.
The X-Series frame features an extended beavertail, deep trigger-guard undercut, and a flat-faced X-Series trigger for consistent press and reset. A reversible magazine release supports left- or right-hand operation, and the integrated MIL-STD-1913 rail accommodates weapon lights or lasers.
The Nitron-finished slide carries forward and rear serrations for confident manipulation. A removable cover plate reveals the PRO optics footprint, compatible with SIG ROMEO1 PRO, Leupold DeltaPoint PRO, and Trijicon RMR patterns. Until an optic is installed, XRAY3 day/night sights provide bright, tritium-powered aiming references.
At its core lies SIG’s modular fire-control unit, allowing caliber or size conversions without gunsmithing. This architecture is shared with the U.S. military’s M18, underscoring the platform’s tested reliability.
Performance is anchored by a carbon-steel, cold-hammer-forged barrel and striker-fired action, delivering duty-grade durability and a clean, consistent trigger pull straight out of the box.
