Although I now understand what you are saying, I don't quite agree.
Although a clip can be a device for charging the magazine of a weapon (stripper clips), it is also a magazine from which cartridges directly feed into the chamber. Your reference to full, half, partial moon clips for pop out or break apart revolver cylinders applies to the latter, yet it also applies to a removable feeder magazine.
It would be most accurate to say that the device in question is a clip AND a removable magazine. To be super technical, it is a clip until inserted, upon which it becomes the magazine.
In such cases of user preferred terminology, you have to at some point concede to the common vernacular. But you do as you wish, you might just be a trend setter.
I have been guilty of calling a revolver a pistol and also committed the terrible sin of saying .45 Long Colt, when of course it is officially the .45 Colt.
