Modifies the offense of unlawful possession of a firearm to include any minor possessing a firearm on public property

HB 1575 modifies Missouri's unlawful firearm possession law to specifically prohibit minors (under 18) from possessing a firearm on public property. This directly affects underage individuals in public spaces like parks or sidewalks, unless they are accompanied by an adult, participating in a school-sanctioned firearm event, hunting legally, or under another authorized circumstance. The law establishes a class C felony charge for this violation (or class B if the minor has prior dangerous felony convictions or prior unlawful possession). It excludes antique firearms from this provision.
