Precision and accuracy are important considerations when shooting your firearm, but they are equally important when talking about your firearm. Using incorrect terminology can lead to confusion, so in order to make the gun community more accurate and precise, let’s address the common misuse of the terms “magazine” and “clip.”
Magazines are storage systems for ammunition that feed the cartridges into the action systematically by means of a spring-driven follower. They can be fixed or detachable; most modern firearms are the latter.
Magazines are the very definition of repeating arms and will be found in anything that isn’t a single shot gun. They may be boxed single stacked, double stacked, rotary, tubular, or even helical.
Stripper Clips or chargers are devices used for rapid and easy loading of ammunition into the magazine. Cartridges are held together on the clip and then manually stripped into the magazine. They are very simple and can be made of anything from steel to cardboard.
Stripper clips were invented and popularized by Paul Mauser and his namesake rifles. They were the standard on military arms until the detachable box magazine became popular.
En Bloc Clip system firearms are slightly trickier. They feature fixed magazine springs and followers, but cannot retain cartridges on their own. The ammunition is held together by an en bloc clip, the whole of which is inserted into the gun. The clip then becomes part of the magazine. When the last cartridge is expended, it is released from the gun.
En bloc clips were popularized by Ferdinand Mannlicher’s rifles. They were often preferred for their speed and ease of loading. The actions, however, were usually left open to allow ejection of the empty clip and were therefore vulnerable to dirt and grit.
I hope this clarifies things somewhat. However, when in doubt, follow the follower. Since a magazine retains and feeds the ammunition it must contain a follower. Simply put, clips hold cartridges, whereas magazines move them.
