The XSeries XFull Pro configuration pairs a 4.7" barrel with the full-size XSeries grip module. The grip features an extended beavertail, a high undercut, and textured panels for confident control. A flat-faced trigger and the striker-fired, modular serialized FCU round out the core P320 advantages.
The slide is finished in black and cut for optics, with front and rear serrations and an external extractor. The installed SIG Sauer ROMEO-X Pro includes a side-load battery door and an integrated rear sight notch that works with the green-dot front post.
Controls are modern and practical, including ambidextrous slide catch levers. A full-length M1913/Picatinny accessory rail with four slots supports duty lights and other rail-mounted accessories. Capacity is 17+1 with the included factory steel magazines.
