Chambered in .357 SIG, this compact P320 configuration offers a 13+1 capacity with a 3.9-inch barrel, balancing shootability and concealability. Its dimensions are 7.2 inches in overall length, 5.3 inches in height, and 1.3 inches in width, with a weight of 28.1 ounces with an empty magazine.
The modular, removable FCU is the serialized component, allowing straightforward grip module changes while retaining the core fire control system. The frame is a glass-reinforced polymer grip module with a push-button magazine release and no manual safety.
The slide is finished in black and cut with front and rear serrations for confident manipulation. Sighting is via durable 3-dot iron sights, delivering a 5.8-inch sight radius for clear, quick alignment.
An integral Picatinny accessory rail provides mounting for compatible lights or lasers. This U.S.-made example carries the EXETER, NH marking adjacent to the FCU window and includes two 13-round, steel, made-in-Italy magazines.
