The term "handgun" was not used until about 1950, when some purists insisted (as many do here) that a revolver was not a pistol and that a term was needed to cover both as well as single shot pistols and the like. So some writers used (or maybe coined) the word "handgun". Gradually, the term came to be used in law and general writing. Up to that point, many gun laws used the term "pistol", as for example banning the carrying of "pistols" without a license. In case you wonder, quite a few people paid fines or went to jail for carrying revolvers; judges didn't nitpick esoteric terminology.
So if your state law still refers to "pistols", I strongly suggest you not do what ever you shouldn't do and then argue that you used a revolver and the law doesn't apply.
