This is a "clip", from an M1 Garand.

This is a Magazine.

[null and void]

A clip hold a bunch of bullets ready to be loaded into a firearm.

A magazine goes into or attaches to the firearm and has a spring to feed individual rounds into the chamber.

I think the key difference is the ability to insert individual rounds into the guns loading mechanism.

One thing for sure, if I'm wrong a FReeper will correct me!
