    What’s Included
    • SIG Sauer factory hard case with 320F-9-B label
    • 1x 21-round magazine and 4x 17-round magazines

    The full-size P320 format delivers a long sight radius and a 4.9-inch barrel, combined with a light gray slide finish and a black polymer grip module. The modular, removable fire-control unit (FCU) allows the user to swap grip modules if desired, and this package includes two additional P320/P250 grip modules.

    This pistol is set up with a red fiber-optic front sight and a square-notch rear sight featuring two green fiber-optic rods. It originally shipped with contrast sights under factory configuration code 320F-9-B and has been updated to the current fiber-optic sight set.

    Controls and handling are straightforward with a push-button magazine release and a flat/straight trigger shoe. Capacity is 21+1 with the included extended magazine, and four additional 17-round magazines are provided. The dustcover carries a multi-slot Picatinny rail for mounting compatible lights or accessories.

    Marked "Made in United States" with an EXETER, NH marking on the grip module, this example corresponds to factory code 320F-9-B, with the case label dated 07-DEC-2016.
