Do not send (or ask a dealer to send) just the frame to the factory. They will not work on it because they cannot test fire the gun after repairing it. They will either return the frame with no work done, or keep it and notify you to send the rest of the gun.
For shipping purposes under the law, a frame is the same as a gun, so you save little or nothing in shipping just the frame.
