OR is a shall issue state for residents. For non-residents, of
contiguous states only, it's still discretionary issue.
Non-residents can go to any county sheriff, but it's discretionary.
Non-resident permits are fully discretionary.
ORS 166.291 (8) The county sheriff may waive the residency requirement
in subsection (1)(c) of this section for a resident of a contiguous
state who has a compelling business interest or other legitimate
demonstrated need.
The word "may" is rather important in this context.
Compare that language to the resident part of the ORS:
ORS 166.291 (1) The sheriff of a county, upon a person's application
for an Oregon concealed handgun license, upon receipt of the
appropriate fees and after compliance with the procedures set out in
this section, shall issue the person a concealed handgun license if
the person...
That "shall issue" makes all the difference.
Clatsop County Sheriff's Office in Astoria used to be the place for WA residents to go as their best bet for getting an OR CPL, but word has it that some folks have recently contacted Clatsop County and were asked to direct their queries and applications elsewhere: it wasn't that the attitude has changed,
but they've been flooded with requests.
It wouldn't hurt to much to give them a call, say you're DaBunny, and ask them about applying.
