The M18 Military pistols are manufactured on the MHS line at SIG.  The MHS Line is authorized by the US government to build their M18’s.  These are not replica M18’s…these are the actual M18 that are built for the Government.  The controls and internals are 100% same as what is issued and used in the US Military.

The Sig Sauer M18 was recently issued to all branches of the U.S. Military and was chosen as the official sidearm of the U.S. Marine Corp. 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, and it includes (1) 17 round magazine and (2) 21 round magazines.
