The M18 configuration pairs a compact 3.9-inch barrel with a carry-length coyote-tan polymer grip module, providing the familiar MHS-inspired profile. The slide wears a durable coyote-tan PVD finish with black controls, and the serial prefix is "M18," consistent with the model’s convention.
Built on the modular P320 fire control unit, this pistol allows the user to swap compatible slides and grip modules within the P320 family. It is a striker-fired system with an ambidextrous manual thumb safety and ambidextrous slide catch levers.
Sight and slide features include factory sights with a dovetailed front and a rear sight mounted to a removable cover plate, plus front and rear slide serrations for positive manipulation. An integrated 1913-style accessory rail on the dust cover supports common weapon-mounted accessories.
Capacity is 21+1 with the extended magazines. This example includes two 21-round and one 17-round SIG Sauer factory steel magazines for the P320 M17/M18 pattern. Country of origin is the USA, and overall length is approximately 7.25 inches (factory spec).
