Issued for law enforcement use and subsequently released as surplus, this XSeries XFull Pro offers duty-grade configuration with civilian availability. The as-new condition and inclusion of the factory-installed SIG ROMEO-X optic add immediate readiness for range or duty-style roles.
The XSeries feature set is prominent: a flat-faced trigger, an XSeries Full-Size grip module with aggressive texturing, an extended beavertail, and an undercut trigger guard for a secure, consistent hold. The striker-fired action and lack of external manual safety levers deliver a straightforward, consistent trigger press.
The full-size slide and 4.7 inch barrel provide a long sight radius and smooth cycling. The slide wears a Nitron black finish with front and rear serrations and an optics cut using the SIG PRO footprint. A SIG X-RAY3 Day/Night front sight with a green outline remains visible even with the mounted red dot.
Modularity is built in. The serialized stainless-steel FCU enables caliber and size swaps within the P320 ecosystem. A 3-slot Picatinny accessory rail supports lights or other accessories. Capacity is 17+1, and three magazines are included to keep the pistol range-ready.
This package highlights practical upgrades and provenance: a law enforcement issue P320 XSeries XFull Pro, surplus to the civilian market, with excellent bore condition and a clean, inspection-only overall condition.
