SIG Sauer P320 Professional 9mm Full-Size Striker-Fired Pistol | Agency Vault Law-Enforcement Allocation
The P320 Professional delivers SIG Sauer’s proven striker-fired performance in a full-size, duty-ready package built for law-enforcement contracts and released to the civilian market only through aftermarket channels. This Agency Vault example combines a modular stainless-steel fire-control unit with a PRO-cut, optics-ready slide, X-Series flat trigger, and X-RAY3 night sights—offering a factory-fresh platform that stands out for its limited availability and mission-driven features.

Built on SIG’s modular platform, the serialized stainless-steel fire-control unit allows caliber and size conversions, giving owners flexibility to configure the pistol for varied roles without additional paperwork.
The full-length carbon-steel barrel measures 4.7 inches, matched to a black Nitron slide featuring front and rear cocking serrations and PRO-cut mounting footprints for SIG Romeo1Pro and Leupold DeltaPoint Pro optics—no adapter plates required.
An X-Series flat-faced trigger breaks at 90° with a shorter reach, promoting consistent finger placement and a crisp press. The striker-fired action maintains a familiar P320 feel while meeting duty requirements.
Night-time readiness comes from SIG’s X-RAY3 tritium sights: a high-visibility green front dot paired with a square-notch rear, offering clear sight pictures in changing light.
A five-slot MIL-STD-1913 rail on the dust cover supports lights or lasers, and the X-Series polymer grip module provides an ergonomic, high-under-cut hold. As part of SIG’s Law Enforcement allocation, civilian examples like this are scarce, adding to its appeal for shooters and collectors seeking a duty-grade package straight from the Agency Vault.
