SIG Sauer P320 X-Series Compact Professional 9mm – Optics-Ready, Night Sights, 15+1 Capacity
Built for duty and released from SIG Sauer’s Agency Vault law-enforcement allocation, this P320 X-Series Compact Professional delivers service-grade reliability in a civilian-legal package that rarely reaches the open market. Its modular stainless-steel fire-control unit, optics-ready Nitron slide, and X-Ray3 tritium sights combine to offer a versatile, carry-sized pistol that’s ready for direct-mount red-dot use right out of the box.

Produced specifically for police and government contracts, the Professional-series P320 Compact features SIG’s flat-faced X-Series trigger for a consistent 90-degree break and shortened reset that promotes fast, accurate follow-up shots.
The Nitron-finished stainless slide is factory-cut for SIG Romeo2, Romeo1T, or Leupold DeltaPoint Pro optics, while deep front and rear serrations and lightening cuts provide positive manipulation and reduce reciprocating mass.
An extended beavertail, high under-cut trigger guard, and interchangeable polymer grip module give the shooter a higher bore axis and improved recoil control without adding bulk, keeping the pistol easy to conceal with its 3.6-inch stainless barrel.
The P320’s modular fire-control unit is the serialized component, allowing caliber or grip-size changes without an additional FFL transfer—one firearm, multiple configurations.
Selected as the basis for the U.S. Army’s M17/M18 sidearms, the P320 platform offers proven durability, and this Professional-line variant carries that pedigree with premium night sights, full-length steel rails, and a 15+1 standard capacity.
