For a law student, you should know that such a ridiculous statement would be ignored on this forum. It is fine to like the .40, but it is not necessary to pull numbers out of thin air.
Since pulling numbers out of the air and rabbits out of the hat of confusion is consistent with the more successufl members of that profession, he might be on the way to a great career.
It's true that, on this forum, simply pointing out that the .40 has long since proven itself on the street would probably have sufficed. And that the 9mm with the best ammo available isn't all that far behind.
