According to the info below from handgunlaw.us , if you're in Portland you're pretty much SOL. If not, you may fall into the meanings below depending on your location.
Another prime example of the critical need to KNOW THE LAW.

From the Oregon Firearms Federation:
OREGON has no STATE law against carrying a loaded handgun in your car as long as it’s : (a) Not concealed or (b) “Not readily accessible.”
“Not readily accessible" (for now) means:
(4)(a) Except as provided in paragraph (b) of this subsection, a handgun is readily accessible within the meaning of this section if the handgun is within the passenger compartment of the vehicle. (b) If a vehicle has no storage location that is outside the passenger compartment of the vehicle, a handgun is not readily accessible within the meaning of this section if: (A) The handgun is stored in a closed and locked glove compartment, center console or other container; and (B) The key is not inserted into the lock, if the glove compartment, center console or other container unlocks with a key. However, localities are allowed to regulate loaded firearms in “public places” which now includes your car. This only applies to people without CHL’s.
So you need to check local regulations. In Portland, for example, you may not have a loaded gun anywhere in your car and you may not even have loaded magazines separate from the handgun. It must still, however, be either visible or “not readily accessible."
