Final thought on this is that I'm not sure what you're trying to accomplish by carefully saying that a gun is a tool for projecting force at a distance. By that reasoning, using an axe on a person would be equivalent to using an axe on a piece of wood, as long as the motion was the same. I don't think it's sound policy to say that axes should be outlawed because axe murders are using them for their intended purpose.

Different kinds of guns have different intended functions, and if you're going to talk about primary uses, this seems important to acknowledge that.
