Senate Bill 5535 (read 01/28/25) would reenact and amend RCW 9.41.010, create a new legislative-findings section, and repeal several 2023 session-law provisions and three coded statutes: RCW 9.41.390, RCW 9.41.395, and RCW 7.48.330. The new section declares that the Second Amendment and Article 1, section 24 of the Washington Constitution protect the right to bear arms and states that any state law creating firearms‑industry liability or banning a particular type of firearm is unconstitutional, ineffective, void, and unenforceable. The bill substantially revises and adds many definitions and procedural terms related to firearms, magazines, transfers, manufacture, and storage. Defined terms shown in the provided text include antique firearm; barrel length; bump‑fire stock; dealer, licensed dealer, and licensed collector; large capacity magazine (>10 rounds) and exclusions; secure gun storage (locked device and unloaded firearm); import and transfer (with an exception for returning to Washington with the same large capacity magazine); unfinished frame or receiver and a multi‑factor “readily” test; untraceable firearm (firearms made after July 1, 2019, lacking a traceable serial number); and creation of a "Washington state patrol firearms background check program" to conduct background checks for transfers and dispositions. The bill also states a presumption that a part identified with a serial number is a frame or receiver unless the ATF or other reliable evidence determines otherwise. Legally, the measure creates a new statutory section (legislative findings), amends and reenacts existing statute language (RCW 9.41.010) and introduces numerous definitional and procedural changes, establishes an administrative background‑check program, and repeals existing statutory prohibitions and consumer‑protection and public‑nuisance provisions related to assault weapons and the firearm industry. The provided text is incomplete: the full amended text of RCW 9.41.010 and subsequent operative provisions, the complete definition of "frame or receiver" (truncated here), the final status of assault‑weapon language shown with deletion markers, and any specific penalties or enforcement mechanisms are not included in the extracted material.

If enacted, the bill would effectively roll back several 2023 measures by repealing the state’s assault-weapon prohibitions and consumer-protection/public-nuisance rules tied to the firearms industry and includes a legislative finding that laws creating industry liability or banning particular firearm types are void. At the same time it adds detailed definitions (for things like frames/receivers, unfinished and untraceable firearms, large-capacity magazines, secure storage, and what counts as a transfer) and creates a named Washington State Patrol unit to conduct background checks for all firearm transfers and dispositions; it also establishes a presumption that a part stamped with a serial number is a frame or receiver unless the ATF says otherwise. The groups most affected would be firearm manufacturers, importers, and dealers (who would likely face reduced state-level liability risk and regain options to make, import, or sell items previously restricted), the Washington State Patrol (which would take on or formalize responsibility for running statewide background checks, implying new or expanded operational duties and costs), and law enforcement and courts (which would rely on the new definitions when evaluating offenses). Key implementation details, timing, and any penalties or enforcement processes are not included in the extracted text, so how quickly and precisely these changes would take effect or be applied remains unclear.
