The XFULL PRO configuration delivers a full-size grip and a 4.7 inch barrel for a stable sight picture and controlled recoil. The flat-faced trigger aids consistent finger placement, while the extended beavertail and deep trigger-guard undercut promote a high, comfortable grip. Ambidextrous slide-catch levers and a left-side takedown lever support efficient manipulation.
The stainless-steel slide wears a black Nitron finish and features front and rear serrations with no lightening windows. It uses the SIG PRO optics footprint and integrates the rear sight into the optic, with the XRAY3 green-dot front post retained. The M1913/Picatinny accessory rail provides four usable slots for lights or other rail-mounted accessories.
The ROMEO-X red dot arrives factory installed. It uses a 7075-T6 aluminum housing, a low deck height that allows co-witness with standard-height irons, and a side-load CR1632 battery. The optic is compatible with the SIG PRO footprint and presents a red reticle for fast target acquisition.
Internally, this P320 employs a striker-fired action with striker safety and disconnect safety. The modular, serialized stainless-steel fire control unit (FCU) supports SIG's P320 design ethos. This pistol was issued for law-enforcement personnel and later made available to the civilian market as surplus. The included case label shows model W320F-9-BXR3-PRO-RXX and date 23-OCT-2024.
