Without seeing the gun and determining why the barrel is loose (and what else is wrong), it is hard to suggest a method of repair. If the frame is cracked, the gun is toast; there is no reasible way to repair it even to fire .22's. If the barrel is merely loose, some of the suggestions may be feasible. But in any case, "fixing" the gun in such a way that it will be dangerous to the shooter is not the way to go.
Maybe it is different in your area, but the local gunsmith is completely out of spare eyes and fingers, and probably can't get any more.
