As FOX pointed out, Clip and Magazine are two different things, and shouldn't be used interchangeably. The term silencer, while a misnomer, leaves no doubt as to what it refers to and is a commonly accepted term (despite purists' objections to it).
The original suppressor, invented by Hiram Maxim, carried the trademarked name Maxim Silencer, and early legal terminology for it was (and still is in many cases) "silencer"; the BATFE still uses the term "silencer."
Seriously, it's not that big a deal.
