I remember there used to be a "Double Agent" skin in tf2.gamebanana.com, but it no longer works. This looks very good; it should really have at least a mod.
Also it's weird that Miss Pauling HAD the Double Agent in Expiration date! IT even uses the revolver's sound! If I was the maker of said skin, I would kill myself... That is unless it somehow manages to get into the game.

Anyone can make this a mod?
