I'm sorry, I don't like any scenario where I am only allowed one more weapon.
I love guns. I think they are a piece of art. I have a hard time picking between guns like a parent cannot choose between chirrens.
I am fortunate that I have most everything I really want, and could not wish for more. That said, I would be interested in the FN 5.7, another HK, a Sig 1911, or the SW MP. I would hate to actually have to make the choice, so please don't ask me to.
