Modifies provisions relating to firearms

HB 2469 preempts all local government regulations on firearms, banning counties, cities, and towns from enacting rules about sales, ownership, open carry, or other firearm-related controls - except for ordinances that exactly match state law (sections 571.010-571.070) or regulate open carry/discharge within jurisdictional limits. The bill shields gun manufacturers from nuisance lawsuits and most liability claims (except for negligence or defects), and imposes a $50,000 civil penalty on localities that violate the preemption. It also grants standing to residents to sue jurisdictions enforcing invalid local rules and requires courts to address such cases within 30 days. The bill directly affects local governments, firearm manufacturers, and residents by centralizing firearm regulation at the state level.
