The full-size P320 configuration delivers a 4.7-inch non-threaded barrel that sits flush at the muzzle and a 17+1 capacity in 9mm Luger. Its striker-fired system is paired with a flat-faced trigger for a consistent, straight-to-the-rear press. Ambidextrous slide catch levers and the absence of an external manual safety give it a streamlined control layout.
The slide is stainless steel with a black Nitron-type finish and front and rear charging serrations. It is cut for optics; the cover plate is not present. A MIL-STD-1913 accessory rail on the dust cover supports compatible lights or accessories.
Sight picture is provided by tritium 3-dot night sights with a green TG-H3 front and a tritium 2-dot rear, both dovetailed, with a 6.6-inch sight radius. The sights are marked "TG-H3," and the barrel hood is marked "9mm x 19" for clear chamber identification.
This pistol uses a serialized fire control unit with a windowed plate and a polymer grip module featuring the SIG medallion. The frame is marked "NEWINGTON, NH, USA." It includes two factory 17-round steel magazines and ships in a SIG SAUER factory hard case with the manual.
