Weapons: firearms; waiting period for firearm purchases; provide for. Amends sec. 223 of 1931 PA 328 (MCL 750.223).

This bill amends Michigan's penal code to establish a mandatory three-day waiting period for all firearm sales, requiring sellers to delay delivery of a gun for at least 72 hours after the sale is completed. It directly affects firearm dealers and private sellers by making it a misdemeanor to deliver a firearm to a buyer before this waiting period expires. The legislation also clarifies existing restrictions by prohibiting sales to individuals under indictment for felonies or those legally prohibited from owning firearms, with penalties ranging from misdemeanors to felonies depending on the violation. Sellers must also verify the age of buyers for long firearms, with stricter penalties for repeat offenses involving sales to minors.
