An apparatus for securely storing at least one firearm includes a firearm shackle having a mounting bracket for secure attachment to a fixed structure. A secure extension has a secured portion secured to the mounting bracket and a distant portion movable relative to said mounting bracket. A clasp has a closed state and an open state with the clasp sized to securely engage a grip end of a firearm when in the closed state and to release the grip end when in the open state. The clasp is connected to the distant portion of the extension for movement therewith. A releasable lock permits selective shifting of the clasp from the closed state to the open state. As an additional component, the apparatus may include a barrel retainer for releasably engaging a barrel end of said firearm. The secured portion and the distant portion of the extension may be separated by either a rigid or a flexible separation.
