Prohibits the purchasing of semi-automatic and fully automatic firearms by anyone under twenty years of age

HB 2571 prohibits the sale, lease, loan, or trade of semi-automatic or fully automatic firearms to anyone under 20 years old in commercial transactions (such as stores or online). This directly affects individuals under 20 seeking to purchase these firearms, including those buying online or in person. The bill amends Missouri law to set a minimum age of 20 for such purchases, with exceptions for law enforcement and military personnel on duty. It defines "semi-automatic firearm" as a repeating firearm requiring manual trigger pull for each shot.
