The P320-M18 configuration brings military-style features to a carry-size 9mm platform. The coyote PVD-finished slide and coyote-tan polymer grip module present the correct M18 appearance, paired with a 3.9-inch steel barrel and striker-fired action.
Controls and safety are mission-focused: an ambidextrous manual thumb safety, internal safeties, and ambidextrous/extended slide catch levers support confident handling. The dustcover carries a MIL-STD-1913 accessory rail for weapon-mounted lights or similar attachments.
Sight system and slide details include a SIGLITE front night sight and a removable night-sight rear plate. The slide is cut with front and rear serrations and uses a removable rear sight/optic plate that enables optics mounting when desired.
The modular FCU-based design uses M18-prefix serialization and the slide is marked NEWINGTON, NH, USA. This pistol ships with three 21-round and one 17-round Made-in-Italy steel magazines, delivering a 21+1 capacity with the extended magazines, along with the SIG Sauer factory case and literature. Country of origin is the USA.
