Washington does not require a locking device to accompany the sale of a firearm, although federal law applies, and beginning July 1, 2019 dealers must offer to sell or provide a lock with every firearm sale or transfer and to post a warning that criminal liability may result from storing a firearm unlocked.1 No state statutes require firearm owners to affirmatively lock their weapons.

State administrative regulations may impose locking device or other safe storage requirements.
