The XSeries XFULL configuration delivers a full-size grip module with an integral beavertail and a flat-faced trigger, providing the XSeries ergonomics and control in a duty-length format. It uses Sig Sauer's modular, serialized stainless-steel FCU, allowing the fire control unit to be the serialized component while the polymer grip module remains non-serialized.
The black Nitron-finished slide features front and rear cocking serrations and an optics-ready cut. Sight alignment is straightforward with a high-visibility green-dot front sight paired to a square-notch rear, giving a clean and fast sight picture.
Built on a polymer frame with a stainless-steel receiver, the pistol includes a full-length dust cover with a four-slot accessory rail. The frame is marked "NEWINGTON, NH, USA," and there is no external manual thumb safety.
Chambered in 9mm Luger with a 4.7-inch barrel, the P320 XSeries XFULL uses double-stack P320-pattern magazines with a 17+1 capacity. Three steel magazines are included, offering ample on-hand capacity out of the box.
