You're referring to "stripper clips" that were invented before guns had removable springed magazines. Those are a type of clip (and lead to the term), however the slang term clip doesn't refer to pistol magazines - it's merely slang for a magazine. It's a common misconception and what I was responding to.

In fact, the internal pistol magazine of a C96 pistol is still a magazine, but it loaded by a stripper clip, and some guns like the Japanese Type 3 are fed directly from stripper type clips - but those aren't "speedloaders" as the article suggests.(To juxtapose the concepts completely...)
