It is impossible to give a blanket answer as to whether a slingshot is illegal, as jurisdictions have varying laws regarding the possession and use of slingshots. Many municipalities, for example, have outlawed the use of wrist-supported slingshots, what many have termed to be “wrist rockets.” In some areas, it depends on how you’re using the slingshot, such as for hunting. It is best to consult both state laws as well as municipal ordinances to be clear on what is and what is not allowed in your area.
