Purpose-built for duty use, this full-size XFULL profile P320 uses a modular stainless-steel fire control unit paired with an XSeries polymer grip featuring an extended beavertail and high undercut. The result is a secure, high-grip geometry with a flat-faced trigger for consistent, straight-to-the-rear press.
The slide is stainless steel with a Nitron black finish and practical enhancements: front and rear serrations for confident manipulation, a direct optic mount, and a step-cut muzzle. SIG XRAY3 day/night sights are installed, with a green dot front blade and a black rear notch to provide a clear, durable sight picture.
A factory-installed SIG Sauer ROMEO-X micro red dot tops the slide. Its CNC-machined 7075 aluminum housing is designed for hard use while keeping weight down and the sight picture rapid and uncluttered.
Capacity is 17+1 in 9mm Luger, supported by three factory steel 17-round magazines. A full-length, 4-slot M1913 accessory rail on the dust cover accommodates common weapon lights or other rail-mounted accessories.
This pistol was issued for law enforcement personnel; this surplus model has been made available to the civilian market. The case label is dated 28-OCT-2024, and the example offered here presents in as-new condition with typical inspection handling only.
