M18 9mm Modular Handgun System


The Modular Handgun System (MHS) provides increased lethality, terminal effects, ergonomics, reliability, durability, and maintainability compared to the current handgun to 50 meters.


The M17 MHS is a 9mm full-sized semi-automatic handgun. The M18 MHS and the M18 General Officer (GO) handgun are its compact variants.

The M17 replaces the M9; the M18 replaces the M11; and the M18 GO pistol replaces the M9 GO pistol. Both the M17 and the M18 can be equipped with either a 21-round magazine or a 17-round magazine.
