Relating to the authority of a municipality or county to regulate certain matters related to firearms, air guns, archery equipment, and other weapons and related supplies.

HB 3138 prevents Texas municipalities and counties from regulating firearm transfers, possession, storage, transportation, licensing, registration, or sales of firearms, air guns, archery equipment, or related accessories. It specifically bans local rules on ammunition commerce, discharge at shooting ranges, and requires liability insurance for firearm use. Exceptions allow limited local control over discharge within city limits (not at ranges), zoning, explosive storage (up to 25 lbs black powder per residence), and carry restrictions at public parks, events, or government meetings. The bill directly limits local government authority over these firearm-related matters.
