no nobody has ever built one. browning has designed a lever action that takes box magazines rather than a tube so it is able to take rimless, pointed bullet cartridges but the ammo capacity is not what you would expect, pretty lousy actually. I fully agree with everyone else, the velocity gains of a 9mm through a 16 inch barrel is quite minimal and increase of energy is barely recordable. it's a pretty lousy option for hunting or just about anything else but punching holes in paper. a more solid design like a lever isn't going to offer much improvement over a semi and too long of a barrel can also be a bad thing.
