What you are missing is Newton's third law. "To every force there is and equal
and opposite reaction." To accelerate a bullet you require a force and so there
will be an equal and opposite force on the gun. The fact the these forces
come from magnetism instead of expanding gas is irrelevant. In effect, as well
as the gun pushing out the bullet, the gun pushes itself away from the
bullet - causing a recoil.
