Relating to governmental action that infringes on the right to keep and bear arms in this state.

HB 3934 prohibits Texas state agencies, local governments, and law enforcement from assisting federal agencies in enforcing certain federal gun regulations. It specifically blocks cooperation on federal requirements like gun registries, licensing for ownership, background checks for private sales, or confiscation of firearms from law-abiding owners. The bill also establishes new state protections for the right to bear arms through a new Government Code chapter. It applies to all Texas governmental entities, including counties, cities, and state departments.
