A gun magazine automatic changing apparatus is disclosed. According to an embodiment, a gun magazine automatic changing apparatus is combined with a gun having a barrel, a barrel cover, a receiver connected to the rear end of the barrel, and a magazine chamber. The gun magazine automatic changing apparatus includes: a multi-magazine mount including a plurality of clips each having a holder fitted on a magazine and connectors disposed on both sides of the holder and having fitting units at both ends; and a loading guide including an actuating bar pushing down the connectors of the multi-magazine mount and a holder formed at an end of the actuator bar to be held by a user and disposed under the barrel cover to move forward/backward.

A cover for an ammunition magazine is provided. The cover can include a top wall and a plurality of side walls extending downward from the top wall. The side walls can define a lower perimeter edge and an interior cavity configured for receiving an open end of an ammunition magazine for a firearm. The cover can include a bracket mounting wing extending outward from one of the side walls and a bracket connected to the bracket mounting wing. The bracket can include a vertical portion and a horizontal portion. The cover can used with a set of coupled magazines used with a firearm by placing the cover over an open end of a spare magazine when a primary magazine is inserted into the firearm. The cover can be automatically detach from the spare magazine when the primary magazine is removed from the firearm due to the bracket contacting the firearm.

A cartridge magazine includes a front wall, a rear wall, first and second side walls, a pair of cartridge retaining lips, and first and second nose-dive control springs. The magazine is adapted to contain two overlapping columns of cartridges in a staggered configuration. Each nose-drive control spring includes a resilient shank portion and a case-engageable end portion adapted and configured to engage with a case of a cartridge. The shank portion extends from one of the side walls to the case-engageable end portion. Each nose-dive control spring is adapted to prevent a cartridge from moving into a nose-dive orientation as a breech face of the firearm pushes the cartridge forward toward the inclined ramp of the firearm.

Aspects of a magazine for use with a repeating firearm are described. One unique aspect is that the magazine is fabricated completely from a translucent polymer that is highly resistant to mechanical, chemical, and thermal failures commonly affecting magazines. Another aspect of the magazine is the inclusion of a coupling system fully integrated into the housing that allows magazines to be securely joined together without the use of tools or additional components. A further aspect of the magazine is the easy release button design allowing the magazine to be disassembled by large or gloved fingers without need for a tool to depress the release button.
