Abstract

A non-detachable magazine configured to be used for new manufacture of firearms or configured to replace a detachable magazine of an existing firearm is disclosed. The magazine may be pivotally mounted on a firearm using a hinge pin, allowing the feed end of the magazine to enter and retreat from the magazine well of the firearm. The magazine includes a magazine body and at least one arm connecting the magazine body to the hinge pin. In some embodiments, a firearm can be made compatible with the disclosed non-detachable magazine such that removal of the magazine is tantamount to disassembly of the firearm, and/or removal of the magazine renders the firearm inoperable.
