Thank you for writing me about firearm suppressors. This issue is a strange inconsistency in Washington's firearm law, House Bill 1604 seeks to change the law on firearms so that use of a noise suppression device is legal as long as it is consistent with federal law. You can track the progress of HB 1604 at:

I will be supporting this bill, and hopefully this inconsistency will be corrected.
Thank you for bringing this issue to my attention. Don't hesitate to contact me with any future questions or concerns.
Sincerely,
John McCoy
State Representative
38th District
