Gee. I remember referring to magazines as clips in the early 1960s .... I'm not even sure there WAS a 'media' back then to have originated the usage. And I kind of think that there were things called 'pistols' before there were semi-autos. If a revolver can only be referred to by its specific design configuration, shouldn't we also have to only refer to self-loaders as 'autos' rather than 'pistols'?
I was brought up in a house full of English teachers, but sometimes I think these arguments are the product of an argument in desperate search of a topic.
