This P320 XFULL is an XSeries, full-size 9mm Luger configuration with a 4.7 in carbon steel barrel and a 17+1 capacity. It is law-enforcement issued surplus that has been released to the civilian market, combining duty-ready configuration with as-new condition and complete factory packaging.
The pistol uses Sig Sauer’s modular stainless-steel fire control unit marked NEWINGTON, NH USA, housed in a black polymer XSeries full-size grip module with an extended beavertail and undercut for a high, secure hold. A four-slot M1913 accessory rail on the dustcover supports common lights and accessories, and the slide features front and rear serrations.
The stainless slide wears a Nitron finish and is paired with a flat-faced, striker-fired trigger for a consistent break. Sighting consists of a SIG X-RAY 3 green dot front, with the factory ROMEO-X PRO optic serving in place of a rear sight.
The ROMEO-X PRO is a factory install with an open-emitter design, low deck height, and side control buttons. It uses the DeltaPoint Pro footprint, a side-load CR1632 battery with a side battery cap for easy service, and a durable 7075-T6 aluminum housing. The optic presents a red reticle for quick acquisition.
