I have a M&P I bought in Washington when I lived there and now I live in Oregon. Do I need to register my firearm in Oregon? If so where would I get more info.
Wrong as two left shoes. While firearms registration is illegal on a Federal level, there are local jurisditions (City of Omaha and State of Michigan come immediately to mind) that do ,in fact, require firearms owners to register their firearms.
Nothing wrong with asking but please don't just take our word for it. As you've seen in this thread alone there's a lot of false information out there. look the statutes up for yourself.
