Fox News is reporting that US Army will hold an industry day on July 29 and talk to gun makers about the joint, Modular Handgun System(MHS).
This is to replace M9 as well as everything else. Gun, ammunition, holster. Expected purchase amount is 400,000 pistols. The idea is to have a platform that can use different calibers. The MHS will be an open-caliber competition that will also evaluate different calibers.
