Changes the offense of weapons possession by adding high-capacity firearm magazines

HB 2727 amends Missouri law to prohibit possessing high-capacity magazines, defined as devices holding more than ten rounds of ammunition. This directly affects individuals who own such magazines, making it a class D felony for most violations (except for specific exceptions like law enforcement or museums). The bill replaces existing provisions by adding "high-capacity magazine" to the list of prohibited items under weapons possession laws. Exceptions allow possession for official duties, commercial transactions with authorized entities, lawful industrial use, museum displays, or dramatic performances.
