The P320’s modular architecture features a removable stainless-steel fire control unit that serves as the serialized component. This example is configured as a Compact with a 3.9 in barrel and compact grip, offering a 15+1 capacity in a carry-friendly size.
Factory BSS sights are installed: steel 3-dot tritium night sights with the rear marked "MH3 AQ." These sights provide a clear, durable setup for low-light visibility and are a defining element of this configuration.
The slide wears a matte black finish with front and rear serrations and an external extractor. The carbon-steel barrel measures 3.9 in and features a Nitron (nitrided) finish. The black polymer frame includes a Picatinny/M1913 accessory rail for lights or lasers, a left-side magazine release, and a curved steel trigger. Operation is striker-fired with a short-recoil, locked-breech system.
Three 15-round steel magazines are included. They are marked Made in Italy and have witness holes to 15, matching the pistol’s 15+1 capacity in compact form.
Markings include EXETER, NH, and the pistol is made in the USA. The manufacturer’s part number is L320C-9-BSS, identifying this Compact model with the factory night-sight package.
