In Oregon, the right to bear arms is protected by Article 1, Section 27 of the state constitution.
Oregon is a shall-issue concealed-carry state and is notable for having very few restrictions on where a concealed firearm may be carried. Oregon also has statewide preemption for its concealed-carry laws—meaning that, with limited exceptions, counties and cities cannot place limits on concealed-carry beyond those provided by state law.
Oregon is also an open-carry state, but preemption does not apply to open carry, so cities and counties are free to limit public possession of firearms by individuals who do not have a concealed carry permit. The cities of Portland, Beaverton, Tigard, Oregon City, Salem, and Independence have banned loaded firearms in all public places.
