The P320 XFULL PRO comes from SIG Sauer’s Professional Program, originally configured for law-enforcement use and now made available as surplus. The duty-size 4.7" XSeries format delivers a full-size slide and grip with front and rear cocking serrations and molded texture panels bearing the SIG medallion.
Its modular, serialized FCU chassis allows the grip module and slide assembly to interface around the core fire control unit. This example is striker-fired and uses the XSeries flat-faced trigger for a consistent, straight-back press.
The factory-installed ROMEO-X PRO optic features a 7075 aluminum housing, a P320/DP-Pro footprint, and a low deck height that enables standard-height iron-sight co-witness with the included XRAY3 day/night sights (green-dot front, rear notch). This pairing provides a clear sighting setup without changing the standard sight heights.
Built in the USA and marked NEWINGTON, NH, this pistol retains practical duty features including a full-length M1913/Picatinny dust-cover rail and 17+1 capacity. The Professional Program SKU W320F-9-BXR3-PRO-RXX and the 23-OCT-2024 case label reflect recent production and packaging for agency issuance prior to surplus release.
