One time I was talking to a guy at work and I said something about a banana clip and he corrected me, but banana magazine just sounds wrong so I don't say it. Otherwise I try to use the "correct" terminology even though a lot of firearms manufacturers don't, which makes me wonder if clip is also correct when referring to an ammunition feeding device. Who decides what the definition is that everyone should use? Is it a magazine if, and only if, it has a spring in it?
