    What's Included
    • SIG Sauer factory hard case
    • SIG Sauer P320 owner's manual
    • Three 15-round steel double-stack magazines (marked "MADE IN USA" with witness holes)

    The P320 Compact pairs a compact-size grip module with a 3.9 inch barrel, delivering a balanced profile suited to carry and duty roles. The black polymer grip module features molded SIG SAUER panels for secure, consistent handling.

    It uses a striker-fired, semi-automatic action with a curved trigger and a modular, removable fire control unit (FCU). This design allows the serialized FCU to be easily moved between compatible P320 grip modules and slides.

    The slide is matte black with front and rear diagonal cocking serrations for confident manipulation. Fixed, dovetailed steel sights include a front blade with a white dot and a rear square-notch, offering a durable and straightforward sight picture.

    Controls include an ambidextrous slide catch and no external manual safety. An integral 4-slot Picatinny-style accessory rail provides straightforward mounting for lights or other rail accessories.

    Capacity is 15+1 with steel, double-stack magazines, and the pistol is made in the USA. This example includes three magazines, enhancing readiness for range or duty use right out of the case.
