maybe, that's a little bit closer but the laws your citing have more to do with being issued a CHL than being arrested for intoxication while lawfully carrying. What I should have said in my other reply (regarding 166.293) was that intoxication isn't an offense that would disqualify one from obtaining a CHL. I cant really say any further but imagine if you got arrested for intoxication the firearm would be returned after being released.I dug a bit further, and I think this might qualify :
What I like is your forcing me to read the statutes and read them all in context, never a bad thing. But for general discussion I don't think its generally illegal for being intoxicated while lawfully carrying in Oregon anyways. To get your CHL revoked as the result of an arrest it would have more to do with what else you were doing while drunk, a public intoxication charge would be the least of your worries.
What do I know though, IANAL.
