Interesting.Good question - IDK.
Honest answer.
I just asked Matt how the best-case scenario goes, and he knows I have a CCP - so since we know each other so well, he just gave the best answer for my situation, even knowing/shot a couple AR pisstolinas I own(ed).
You can’t really carry those ‘concealed’ -but are legal to have loaded in vehicle vs a Ruffle ‘potato chip’ - of any style in a vehicle under WA law.
So those tucked in a seat/center console are semi-common up here, and I suspect down there since you’re far enough away from the King County mess-o-life.
I’d walk into the local sheriff office & ask what’s the situation they prefer, but almost expect WSP will hard-line anything, as they are both rolling tax collectors & EMS for the I-5 corridor.
But all WSP are working their 1st LEO job & have apps in w/ local PD’s or esp county sheriff - WSP is just a stepping stone, everyone local knows it.
HTH.
