Seattle is Camden/Newark of the west coast.
Looks like WA is shall-issue, but may require answers to written questions, and perhaps an oral interview. On top of a 30 day waiting period, I’m sure that Covid restrictions could tie things in a pretty good knot. Pre-Covid, my Oregon county had a problem with the fingerprinting process that balled things up for months. I’m sure the cretins in King County government could get creative in their delays.
Have you gone through the process?
