SIG Sauer P320 Pro X-Series Full-Size 9mm Luger 4.7" Law-Enforcement Agency Vault Pistol – 17+1
The P320 Pro X-Series Full-Size combines SIG Sauer’s modular 9mm striker-fired platform with Agency Vault law-enforcement allocation upgrades rarely seen on the civilian market. A nickel-PTFE coated stainless fire-control unit, factory PRO optic cut, and X-Series flat trigger give this pistol duty-grade performance in a configurable package that accepts caliber and frame conversions without an FFL.

The Pro X-Series slide wears a durable black Nitron finish and features forward and rear serrations plus a factory PRO optic cut that accepts SIG ROMEO1 Pro, ROMEO2, or Leupold DeltaPoint Pro without adapter plates. Tritium XRAY3 day/night sights are installed for immediate low-light readiness.
The serialized stainless fire-control unit is nickel-PTFE coated for enhanced corrosion resistance and includes a flat-faced X-Series trigger that delivers a consistent, crisp break. A reversible magazine catch supports left- or right-hand shooters.
An extended beavertail, deep undercut, and medium-size X-Series grip module provide secure control even during rapid strings. The full Picatinny rail allows mounting of lights or accessories, while the 4.7" carbon-steel barrel maximizes 9mm performance in a duty-length slide.
Produced in SIG’s Agency Vault for police and government contracts, this Professional-series P320 is normally restricted to law-enforcement channels; civilian examples like this one are uncommon and sought after.
