The full-size P320 configuration pairs a 4.7 in carbon steel barrel with a nitride-type finish with a 9mm Luger chambering for a 10+1 capacity. Its striker-fired, short-recoil, locked-breech action delivers the familiar P320 fire control with no manual safety.
The slide is finished in black with front and rear cocking serrations and an optics-ready cut topped by a cover plate. Steel 3-dot sights provide a clear picture, and the sight radius is approximately 6.64 in.
The black, glass-reinforced polymer frame houses SIG's Modular Fire Control Unit, visible through a right-side FCU window. Controls include bilateral slide catch levers and a left-side magazine release. An integral 1913 accessory rail with six slots supports common rail-mounted accessories.
Two 10-round steel magazines are included and are marked 'MADE IN ITALY' with witness holes to 10. The FCU serial plate displays '58J703412'; 'NEWINGTON, NH, USA' appears on the frame adjacent to the window, and the pistol is made in the USA.
