Sig Sauer M18

The M18 was recently 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 is the commercial version that brings the same unprecedented accuracy, extreme reliability and unmatched durability the military demands.

The P320-M18 comes standard with SIGLITE night sights and a removable night sight rear plate. The slide is optic ready and directly compatible with the ROMEO1 PRO. The slide and grip module are the same coyote tan as the military version. The P320-M18… chosen by the U.S. Marine Corps and the U.S Military, now available to you for the first time.

*Note: This pistol typically comes with 17rd and 21rd magazines. As these M18’s are very hard to find, when I found a Maryland-Compliant version that comes with 10rd mags, I jumped on it anyway.  See below for part numbers for the correct Sig 17rd and 21rd mags in FDE.
