    The Sig Sauer P320 XSeries XFULL is a modular, full-size 9mm built around the P320's serialized fire control unit. This example features a 4.7 in barrel, a flat-faced trigger, ambidextrous slide catch levers, and a slide with both front and rear serrations plus an optics cut. It ships with a 17-round magazine, uses a durable black polymer grip module with textured panels, and is made in the USA.

    What's Included
    • 1x 17-round magazine

    The XSeries XFULL configuration delivers a true full-size layout with a 4.7 in barrel and full-length grip, providing 17+1 capacity in 9mm Luger. It is a striker-fired, locked-breech, short-recoil design consistent with the proven P320 platform.

    Ergonomics and controls are a highlight: a flat-faced trigger promotes a straight, consistent press; ambidextrous slide catch levers accommodate various shooting grips; and the magazine release is positioned on the left side. This model has no external manual safety.

    The slide is cut with both front and rear serrations for confident manipulation and includes an optics cut. A 3-dot sight system pairs a green front dot post with a dovetailed rear notch carrying two dots, offering a clear, familiar sight picture and an approximate 6.6 in sight radius.

    Built on a black polymer frame with textured grip surfaces, this P320 includes a three-slot accessory rail on the dust cover. Its modular, serialized FCU allows the user to swap compatible grip modules and slides within the P320 ecosystem. Made in the USA.
