The P320 Compact configuration pairs a 3.9-inch steel barrel with a compact grip module for a balanced carry and duty profile. This example is Massachusetts compliant and ships with two 10-round magazines, providing a 10+1 capacity while meeting state requirements.
Controls are thoughtfully executed: an ambidextrous manual thumb safety and ambidextrous slide catch levers support varied handling preferences, while the magazine release is set up on the left side. The curved trigger, striker-fired action, and locked-breech, short-recoil system deliver the familiar P320 operating feel.
The slide wears a matte black finish and uses an external extractor. Sight regulation comes from dovetailed steel 3-dot sights with a white-dot front and a serrated rear notch, and the top end has no optic cut. A five-slot MIL-STD-1913 accessory rail forward of the trigger guard accepts compatible lights or accessories as needed.
The modular, serialized Fire Control Unit (FCU) allows caliber and size conversions using compatible P320 components, adding flexibility for future configuration changes. The FCU serial matches the factory case label for this pistol.
Manufactured in the United States with "NEWINGTON, NH, USA" marked on the pistol, this model corresponds to SIG Sauer part number 320C-9-BSS-MS-MA. The factory case label reflects a date of 12-APR-2022, aligning with this compliant configuration.
