Shared gun in a car

If we keep a pistol in the locked glovebox, and my wife and I both sometimes drive the car what's the legal situation?

I believe that transfers between spouses are unrestricted and WA is a community property state so I think this should be fine. It's just transferring between us when we transfer the car between us.

If we both have a CPL then it should be fine if it's loaded. If one doesn't have a CPL then it should be fine if it's stored unloaded with a loaded magazine that is not inserted in the pistol.

A little more complicated if it's a standard capacity magazine, but should be clear cut for a 10 rounder

Am I right?
