a receiving structure for receiving the barrel of a firearm, said receiving structure disposed within said enclosed interior volume; said receiving structure subjected to an expanding force between said receiving structure and an interior surface of said enclosed interior volume, said expanding force directed towards said container opening;
a receiving structure latch having a latched and an unlatched state, said receiving structure latch preventing motivation of said receiving structure towards said opening when disposed in said latched state, and allowing motivation of said receiving structure towards said opening when disposed in said unlatched state, said receiving structure latch biased into said latched state by a biasing force, and said receiving structure latch further comprising a striking surface;
wherein when said receiving structure latch is motivated against said biasing force such that said receiving structure latch transitions to said unlatched state when said retractable cover operates on said striking surface as said retractable cover is motivated into said open position by operation of said opening force, allowing said receiving structure to be motivated toward said opening by said expanding force so that a handle of a handgun disposed on said receiving structure protrudes at least partially through said opening.
