Wheeler. Just got off the phone with a close Oregon JAG friend of mine. If you are Home of Record Oregon you are still a resident here for CCW permit purposes. When you return you should go to the closest sheriff's office and start the process.
Unfortunately you are not likely to get them to help you do it "absentee." But you might try calling several counties' sheriff's offices and ask.
But you DON'T want a Non-resident permit as that is discretionary issue where resident is shall issue and you qualify!
THANK YOU FOR YOUR SERVICE.
