There are two words that apply to a discussion of whether or not the word "Weapon" applies to "Guns".
a : designed for or understood by the specially initiated alone <a body of esoteric legal doctrine — B. N. Cardozo>
b : requiring or exhibiting knowledge that is restricted to a small group <esoteric terminology>; broadly : difficult to understand <esoteric subjects>
a : limited to a small circle <engaging in esoteric pursuits>
b : private, confidential <an esoteric purpose>
: of special, rare, or unusual interest <esoteric building materials>
: a trite phrase or expression; also : the idea expressed by it
: a hackneyed theme, characterization, or situation
: something (as a menu item) that has become overly familiar or commonplace

He is no fool who gives what he can not keep to gain what he can not lose.
