The modular design centers on Sig’s serialized stainless-steel Fire Control Unit with a right-side serial window and "EXETER, NH" marking. This allows the FCU to be the regulated component while the Compact Medium grip module provides the size and ergonomics for this configuration.
The pistol uses a striker-fired system with a curved trigger and short-recoil, locked-breech operation. Ambidextrous slide catch levers and the absence of an external manual safety define the controls on this example.
Construction features include a stainless slide and a stainless-steel receiver/chassis housed in a polymer grip module. Fixed, dovetailed 3-dot iron sights consist of a front blade with dot and a square-notch rear.
A 3.9 inch barrel pairs with the Compact format and a 13+1 stated capacity in .40 S&W. An M1913/Picatinny accessory rail on the dust cover supports compatible weapon lights or other rail-mounted accessories.
This example is made in the United States and includes one steel magazine for the P320 Compact .40 S&W, marked "MADE IN ITALY" with witness holes at 5/10/13.
