SIG Sauer P320 XCarry Pro 9mm – Agency Vault Law-Enforcement Allocation, 3.9" Optic-Ready Slide, 17+1 Capacity
This X-Series P320 XCarry Pro comes straight from SIG Sauer’s restricted “Agency Vault” law-enforcement production run, making civilian examples uncommon. Built around the modular, serialized stainless-steel fire-control unit, it carries a 3.9-inch PRO optic-ready slide, XCarry grip module, X-Series flat trigger, and tritium day/night sights. All components show factory-fresh condition, with no evidence of use beyond test firing.

Released through SIG’s law-enforcement channel, this XCarry Pro was produced for agency contracts and reaches the civilian market only via aftermarket distribution. The limited availability enhances its appeal to collectors and shooters looking for factory-fresh LE-spec hardware.
The PRO slide pairs carbon/stainless-steel construction with a durable matte-black finish, forward and rear serrations, and a removable optic cover plate housing the two-dot tritium rear sight. Underneath, a five-slot MIL-STD-1913 rail accepts weapon lights or lasers without modification.
The compact XCarry grip module balances 17-round capacity with controllable ergonomics. Its high undercut trigger guard and subtle beavertail promote a consistent, high grip for fast follow-up shots.
SIG’s X-Series flat-faced trigger breaks cleanly and shortens perceived reach, while the striker-fired action keeps the pull smooth and consistent. Combined with the modular fire-control unit, the platform allows future caliber or frame swaps without a gunsmith.
