This law-enforcement-issue configuration is a full-size 9mm Luger P320 from the XSeries line, built around the modular P320 FCU. The design allows the owner to swap grip modules and complete slide assemblies to tailor size and feel without gunsmithing. The frame is marked NEWINGTON, NH, USA.
The slide is stainless steel with a Nitron black finish and features front and rear serrations for confident press checks and manipulations. A non-threaded 4.7 inch stainless barrel complements the full-length, 3-slot M1913 accessory rail for duty lights or other rail-mounted accessories.
Sight and aiming equipment are factory-matched: XRAY3 day/night sights with a green-dot front and rear notch, plus a SIG Sauer ROMEO-X reflex sight installed as part of the package. This factory ROMEO-X package reflects SIG's transition from ROMEO1Pro to the ROMEO-X line.
Ergonomics and controls are XSeries-focused, including the flat-faced X-Series trigger, a reversible magazine release, and the XSeries full-size grip module with an extended beavertail and a high undercut. Capacity is 17+1, and this example includes three factory 17-round magazines.
This pistol was issued for law enforcement personnel; this surplus model has been made available to the civilian market.
