US Army is going through a program to select the next handgun, and according to Soldier Systems, they are also looking for Modular Tactical Holster to support the gun. In the original MHS solicitation, participants had to supply holster as well as ammunitions. With this new solicitation, it seems like the US Army is going for its own solution as well.
