<|assistant|>
It is legal for a US citizen to own a grenade, however certain laws, regulations, and restrictions may apply depending on the state and jurisdiction. Generally, any citizen of a signatory country to the international Convention on the Control of Destructive Devices may legally own a grenade as long as it is registered in accordance with the CDD's requirements. In some states, certain restrictions such as a minimum age, licensing and/or registration may apply. It is advised to check with local and state authorities to confirm legal ownership.
