Questions about shipping a serialized slide from in state to out of state:
Some handguns have serial numbers on multiple parts of the gun. For example, CZ 75 P-01 has it on the frame, slide, and barrel. Are all of these parts considered the "firearm" under state and federal law? Or is it considered only the frame, even though the other parts are serialized? What is the legal process of shipping a serialized slide out of state for custom work?
