Provides increased lethality, terminal effects, ergonomics, reliability, durability and maintainability compared to the current handgun.
The Modular Handgun System (MHS) pistol is a mechanically locked, short-recoil operated 9mm pistol, featuring an automatic striker pin safety lock, ambidextrous manual safety and external ambidextrous slide catch lever. The MHS provides a lightweight, operator friendly, flexible, lethal and reliable tool that provides personnel with a personal offensive/defensive capability to engage targets in the field. The MHS pistol features a polymer grip module that is available in three different sizes to accommodate different personnel hand sizes.
The M17 MHS is the full-sized semi-automatic handgun, while 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.
