The XFULL configuration delivers a full-size 9mm platform with a 4.7-inch stainless steel barrel and a standard 17+1 capacity. It is built on the modular P320 system with a serialized fire control unit and has no external manual thumb safety.
The black Nitron-finished slide features front and rear cocking serrations. A 6.6-inch sight radius pairs with tritium 3-dot night sights and a high-visibility green front dot for clear sighting in varied light.
The X-Series polymer grip module with SIG medallion provides a solid, consistent interface, while the flat-faced trigger supports a straight press. The striker-fired action keeps the controls simple and familiar for P320 users.
A full-length dustcover with a four-slot MIL-STD-1913 accessory rail supports light or laser attachment. Made in the USA, this P320 X-Series XFULL arrives ready with three 17-round steel magazines.
