Massachusetts puts its sweeping 2024 gun law to a statewide vote

Published October 6, 2026 · Updated October 13, 2026

Question 9 on the November 3 ballot asks voters to keep or repeal Chapter 135, the state's firearms overhaul. It is the first time voters anywhere will pass judgment on a post-Bruen blue-state gun package, and California is watching.

Who this affects: No direct change to California law. The referendum is a bellwether: its outcome will influence what gun legislation blue-state legislatures, including Sacramento, pursue in 2027. California's own rules on background checks, dealer-recorded transfers and assault-weapon definitions remain exactly as they are.

Massachusetts voters will decide on November 3, 2026 whether to keep Chapter 135 of the Acts of 2024, the sweeping firearms law the legislature passed two years ago. The measure appears as Question 9, a veto referendum, which means the vote runs in reverse of what many expect: a yes vote keeps the law, and a no vote repeals it.

What the law does

Chapter 135 has been in force since October 2024 and was never suspended while the referendum qualified. Reporting from WBUR, WGBH and the Daily Hampshire Gazette describes a broad package: expanded background checks, new rules for self-built (ghost gun) firearms including serialization, a wider red-flag law, prohibitions on carrying in certain public places, and a shift from the "assault weapon" label to a broader "assault-style firearm" definition. The law also requires owners to register firearms through the state's new MIRCS portal, with compliance deadlines falling in October 2026 even as the vote approaches.

Where the vote stands

A MassINC poll of 800 likely voters taken September 14-22 found 70 percent in favor of keeping the law and 18 percent for repeal. Repeal supporters argue the law burdens lawful owners without touching violent crime; supporters of the law call it a national model. Because the law stays in effect unless repealed, Massachusetts owners are being advised to keep complying through the vote.

Why it matters beyond Massachusetts

Question 9 is the first time a state's voters will directly keep or kill a comprehensive post-Bruen gun package at the ballot box. The result will be read as a signal in every state weighing similar legislation, California included: Chapter 135's combination of expanded definitions, carry restrictions and registration goes further in places than California law, which records transactions through dealers at the point of sale but has no retroactive register-everything mandate. A lopsided result in either direction will shape what legislatures attempt next year.
