    What’s Included
    • Sig Sauer factory plastic hard case
    • Two 10-round steel magazines

    The XSeries XFULL configuration delivers a full-size 9mm platform with a 4.7 inch steel barrel and a striker-fired action. The flat-faced trigger provides a consistent, straight-pull feel, and the textured polymer grip module with extended beavertail helps maintain control during strings of fire.

    California-compliant features include an ambidextrous manual safety and a top-mounted loaded chamber indicator marked "LOADED WHEN UP." This model ships with two 10-round steel magazines to meet state requirements.

    The slide is finished in matte black and includes a factory optic cut with a two-screw cover plate installed. Sighting is straightforward with fixed 3-dot sights: a high-visibility green dot front paired with a two-dot rear.

    Built on Sig Sauer’s modular system, this pistol uses a removable stainless-steel fire-control unit (the serialized component) housed in a polymer grip module. The dust cover integrates a 4-slot Picatinny accessory rail for lights or lasers, and the pistol is made in the USA.
