    What's Included
    • Original case
    • 3x 17-round steel magazines (flush steel baseplates, with 'MADE IN USA' stamp and witness marks)
    • Recoil springs

    The TXG tungsten-infused X-Series grip module gives this Legion model its distinctive feel and balance, with aggressive grip texture, SIG medallions, and an installed flared magwell. Capacity is 17+1. Compatibility note: With the installed flared magwell, the included flush-base 17-round magazines typically will not fully seat or lock; use extended base pads (e.g., Legion/Henning type) or remove the magwell to run these magazines.

    The 5-inch, match-grade bull barrel is paired with a striker-fired system and a flat-faced, skeletonized trigger. A one-piece steel guide rod with 1911-style springs (Legion spec) supports consistent cycling.

    The Legion Gray PVD slide is cut with front and rear serrations, top lightening windows, and an optic-ready cut. Factory markings include 'SIG SAUER P320' and 'Xfive.' The fully adjustable rear sight is mounted on the optic-cover plate, and the front sight uses a green fiber-optic insert. Sight radius is 6.8 inches.

    The dustcover features a full-length M1913 accessory rail. Factory dimensions are 8.5 inches overall length, 5.8 inches height, and 1.6 inches width. Weight is 43.5 ounces with magazine. Made in the USA.
