Representative implementations of devices and techniques provide a holster mount assembly, to mount and to support an implement (such as a handgun, for example) or an implement holster (such as a handgun holster or shell, for example), or the like, in a variety of configurations. The holster mount assembly is arranged to be worn on a user's person, clothing, or gear (backpacks, gear packs, accessories, straps, belts, etc.), for example, for temporarily and safely carrying the implement, while making the implement easily accessible to the user. In various embodiments, the holster mount assembly is comprised of two primary components, where one of the two components is coupled to the implement or implement holster.
