The P320-M18 follows the factory M18 spec with a 3.9 inch barrel and carry-spec dimensions, delivering a carry-length grip module and striker-fired operation. The serialized stainless-steel fire control unit is marked NEWINGTON, NH, USA, aligning with the commercial M18 configuration.
The stainless-steel slide wears a coyote tan PVD finish and includes front and rear cocking serrations. Sighting is handled by a SIGLITE front night sight and a removable rear night-sight/plate assembly secured by screws, providing a clear 3-dot night sight picture.
The coyote polymer grip module has molded texture and SIG SAUER logos for consistent control. An integral Picatinny/M1913 accessory rail with three slots on the dust cover supports common lights and accessories. Controls include an ambidextrous manual safety and ambidextrous slide catch with a curved trigger.
Capacity is flexible with the included magazines: two extended 21-round magazines and one 17-round magazine, all with coyote floorplates. The magazines are steel and marked Made in Italy, matching the P320/M18 pattern. This example is in very good overall condition with an excellent bore.
