SR3 says a weapon focus adds it's Force to the user's appropriate combat skill when wielded in combat. Does this mean that if my Adept bonds with a melee hardened handgun weapon focus, he gets this bonus when he shoots with it AND melee attack with it, or just when I melee attack with it?

Just for melee ...

There are no magical ranged weapons to date. Either you have anchored bullets but there is no magical weapon like the magic bow or something.

Like Cochise says.
