The bill seeks to strengthen the rights of individuals to bear arms in Washington State, affirming that both the Second Amendment of the U.S. Constitution and Article 1, Section 24 of the Washington State Constitution safeguard this right. It declares any state law that imposes liability on members of the firearms industry or bans specific types of firearms as unconstitutional, thus rendering such laws ineffective, void, and unenforceable. Additionally, the bill introduces a new section that emphasizes the protection of individual rights to bear arms, while also reenacting and amending RCW 9.41.010 to include various definitions related to firearms.

Significantly, the bill deletes the previous definition of "assault weapon," which specified certain firearms and characteristics, and introduces new definitions such as "large capacity magazine." It also includes a range of new terms related to firearms and mental health professionals, such as "nonimmigrant alien," "secure gun storage," and "Washington state patrol firearms background check program." By repealing outdated or redundant provisions, the bill aims to update and clarify existing laws regarding firearms, particularly in relation to sales, transfers, and storage, thereby enhancing the state's ability to manage firearm-related issues effectively.
