A magazine is the storage area and feeding device for ammunition in a firearm which is attached to a repeating firearm. When a firearm holder fires a gun, the magazine operates by relocating the cartridges stored inside into a location that it can be fed into the chamber to create impact. A removable magazine is normally called a ‘clip’ and are heavily regulated by gun control laws because it is an important piece of most repeating firearm.

Gun magazines are made in many shapes and sizes ranging from bolt action express rifles, that hold only a minimum amount of rounds to machine guns that contain hundreds of rounds. The guns that can utilize a wide variety of magazine usually use a box or drum magazine and some firearms can even feed from both magazines and belts. The most commonly used of magazine in modern firearms are the removable box type magazines. This cartridge in this magazine is stored in either the column in a staggered zig zag manner or with each bullet placed one above the other. When the firearm starts to fire, then the cartridges are shifted to the top of the magazine by another follower driven by spring tension to either a side by side or a single feed position.

Certain gun magazines such as the single or multiple tubular magazine are usually found on most lever action rifles, and pump action shotguns whether round or flat nose. These magazines store cartridges end to end inside of a spring loaded tube, running parallel to the barrel or in the buttstock and is normally directly attached to the firearm when being used. The main problem with tubular magazines was that when the bullet tip makes impact with the primer of the cartridge ahead of it during recoil, it would sometimes iginite which made it very dangerous to use so the military eventually stopped using these magazines when the pointed ‘splitzer’ bullets were introduced.

There are also cylindrical designed magazines like drum and rotary magazines that let you put more bullets inside than box magazines. Drum magazines are used primarily in light machines guns such as the Heckler & Koch MG36, but these magazines are less reliable and complicated. In some drum magazines, the cylindrical chamber forces the loose rounds into an exit slot while the cartridge is stored parallel to the axis of rotation. When the magazine is filled, then a wound spring forces the partition against the rounds. A single staggered column is pushed by a follower through a curved path. From there the rounds enter the vertical riser either from a single or dual drums. Other types of magazines include, Pan and Helical. There are also exceptionally high capacity magazines that were made to hold way more cartridges that the normal capacity but those magazines are prohibited. Magazine capacity is often limited by the design of the firearm, like for example internal, tubular, or rotary ones. A lot of pistols and rifle magazines are considered as “high capacity” by gun regulatory laws are really the factory standard magazines were initially designed for use with their respective firearms.
