Relating to prohibiting certain transfers, purchases, and possession of firearms; creating a criminal offense.

HB 306 prohibits individuals under 21 from purchasing or possessing firearms, creating a Class A misdemeanor offense. It also amends existing law to ban selling firearms to minors under 18 (without parental consent), people under 21, felons within five years of release, intoxicated individuals, and those subject to active protective orders. The bill imposes stricter penalties, including state jail felonies for certain violations like selling handguns to minors under 21. It directly affects young adults, minors, and individuals with specific legal restrictions related to firearm access. The bill focuses on restricting firearm transfers and sales through defined prohibitions, not on broader policy changes.
