Dude, this is sweet.

But a quick FYI, clips and magazines are different things. Magazines are devices that hold multiple cartridges, and are most easily identified by having a spring. (All repeat loader weapons have a magazine.) Some magazine are removable, such as the box magazine in your drawing, and some integral, like the tubular magazine in a 12ga. pump action.

A clip, on the other hand, is a whole piece of metal used to make loading a magazine easier. A clip is never built in to a weapon. Some different kind of clips are stripper clips, used to quickly load box magazines, and drop in clips, which drop directly into a magazine designed to fit it. (Like the M1 Garand clip.)
