Yes—suppressors (also known as silencers) are legal to own and use in Washington state as of 2025, provided you meet certain federal and state requirements.
As of 2011, Washington state legalized suppressor ownership. But it wasn’t until 2014 that the state permitted lawful use (RCW 9.41.250 was updated to allow it). Today, Washington is considered a suppressor-friendly state, but you’ll still need to comply with federal NFA rules.

Only if the other state allows suppressor ownership. Never bring one into CA, IL, HI, or other restricted states.
