The P320-based M18 pistol is currently issued to all branches of the U.S. Military and was chosen as the official sidearm of the U.S. Marine Corps. The P320-M18 California Compliant brings the same unprecedented accuracy, extreme reliability, and unmatched durability the military demands in a California-compliant commercial version.  

The P320-M18 California Compliant comes standard with SIGLITE night sights and a removable night sight rear plate. The slide is optic-ready and directly compatible with the ROMEO-X, ROMEO1 PRO, and ROMEO 2 red dot optics. The slide and grip module are the same coyote tan as the military version, and it includes (4) 10-round magazines. The P320-M18...chosen by the U.S. Marine Corps and the U.S. Military, is now available in California for the first time.
