While the magic weapon is active, you lose any effects (immunities, extra attacks, etc) that you were being granted by weapons you were holding, either in your main hand or your off-hand... but you retain any benefits being granted by a shield. (You need to equip the shield before you MMM, though.)

Not a huge deal since your Meteor-thrower probably isn't on the front lines, but you could, say, give them the Shield of Fyrus Khal and have them do MR-spreading duty right behind your melee-ers.
