The Legion configuration brings a purpose-built, full-size 9mm with a 5" barrel and a gray grip module that includes SIG medallions and a flared magwell. The serialized FCU is visible through the frame window, underscoring the modular P320 design.
Sight setup is fast and precise: a green fiber-optic front sight pairs with a fully adjustable rear. The flat-faced, skeletonized trigger supports a consistent, straight press, aligning with the XFIVE's performance focus.
The slide is optics-ready and includes a cover plate with the chevron mark. It features three large top lightening windows and front and rear serrations for confident manipulation. Slide markings read SIG SAUER P320 and X-FIVE, and the barrel hood is stamped 9mm x 19.
A full-length 5-slot Picatinny rail runs the dustcover for accessory mounting. Capacity is 17+1, and this pistol ships with three factory steel magazines made in the USA, each with witness holes marked 5/10/17.
