I don't know how you can call the Halo 1 pistol balanced, or even slightly-balanced. It was really, really unbalanced, and needs changes. I will admit that the Magnum was worthless, so they need to beef it up a bit, but it still needs to be weaked considerably. It shouldn't be able to take down people with, say, a Battle Rifle or Assault Rifle, or basically any other gun. I guess it should help you stand a chance, but not easily beat other weapons, like it was in Halo 1.
