The SIG Sauer P320-M18 is the commercial version of the M18 being adopted by all branches of the United States Military. It is built to the same standards with all the same features like an ambidextrous manual safety and a compact coyote brown frame. It uses the modular chassis system, so it is compatible with other frame sizes that are designed for use with the manual safety chassis. The compact frame is designed for ergonomics with a slightly undercut trigger and a high beavertail allowing you to get a high grip for better recoil management. It also utilizes a standard picatinny rail for mounting lights and lasers. The SIG M18 Civilian 9mm Pistol comes with one 17 round magazine and two 21 round magazines. An excellent addition to anyone’s military firearm collection.
