    • Manual

    The optics-ready slide includes an optic cut covered by a removable cover plate, plus front and rear serrations and an external extractor. The combination of a matte stainless finish and dovetailed steel sights (white-dot front, plain square-notch rear) provides a clean, durable setup ready for direct optic installation with the appropriate footprint.

    The serialized stainless-steel fire control unit is the heart of the P320’s modular design and is visible through the right-side window. Paired with a polymer grip module and a full-length M1913 Picatinny rail on the dustcover, it supports straightforward accessory mounting while keeping the platform adaptable.

    Controls are practical and user-friendly: an ambidextrous slide catch lever and a reversible magazine release accommodate a wide range of shooters. The striker-fired action uses a curved trigger, maintaining a familiar interface across the P320 series.

    Chambered in 9mm Luger with a 4.7-inch stainless barrel, this full-size variant offers a standard 17+1 capacity. It comes well-outfitted with one 17-round steel magazines, providing ample range or duty readiness out of the box. The frame is marked Newington, NH, USA.
