The purpose of this legislation is to lower the minimum age for purchasing a handgun from 21 years to 18 years. This change aims to expand the rights of younger adults, particularly those who are eligible to vote, by allowing them to obtain handguns legally from licensed dealers. The key provisions of the legislation include amendments to existing laws that currently prohibit individuals under 21 from purchasing handguns. Specifically, it removes the age restriction that prevents those under 21 from obtaining handguns from federal firearms licensees.
