From Oregon Firearms Federation website's FAQ page -
Oregon has no prohibition on carrying loaded handguns in your car. But the state DOES allow localities to restrict loaded carry of firearms ?in public places? which, oddly enough, includes your car.If you are in a place like Portland or Oregon City that restricts loaded carry by people who do not have concealed handgun licenses, you may not have a loaded firearm in your vehicle. Furthermore, if it is a handgun, it must be carried openly or ?not readily accessible.? That means if you have a trunk it must be there. If you don?t, it can be in a locked glove-box, center console or other locked container and if the container is opened by key, the key cannot be in the container.
So, I either find a way to mount it high on the dash, or find a gun vault I would be comfortable using. I can see I'm still going to have questions to ask about carrying. Although I do see the likelihood of using the gun vault anyway, because of the possibility of an accident
