HRS §134-10
Alteration of identification marks prohibited
This law makes it illegal to change, remove, or wipe out the identifying marks on a gun or ammunition, like the make, model, or serial number. If you have a gun or ammo with such marks messed with, the law assumes you did it. This is a narrow rule about tampering with identification.
