Built on Sig's modular platform, this P320 uses a stainless-steel fire control unit (FCU) as the serialized component, visible through the frame's serial window. The full-size .45 ACP setup pairs a 4.7-inch barrel with a .45-specific grip module and 10-round, single-stack magazine.
The control layout is designed for versatility, with ambidextrous slide catch levers and a reversible magazine release. It is a striker-fired system with an internal striker safety and disconnect safety and has no external manual safety.
Target acquisition is straightforward with dovetailed sights: a white-dot front and a square-notch rear. The slide wears a matte black finish and is machined with both front and rear serrations for positive manipulation.
The polymer frame incorporates an integral 1913-style accessory rail for mounting compatible lights or lasers. Markings include 'SIG SAUER P320' on the slide, '45 AUTO' on the barrel hood, and 'EXETER, NH' on the frame. The included steel magazine is marked 'Made in Italy.' Capacity is 10+1 as configured.
