If you're legal where you live and legal at your destination, Fed law allows you to transport your firearm legally*. If you're driving and passing through jurisdictions where you are not legal to carry on your person or in the passenger compartment of your vehicle, then you need to carry it unloaded, apart from ammo, and preferably in its own storage container (not a holster) in the trunk. The point is that it is not available/accessible by anyone in the passenger compartment.

If you haven't done so already, look here: Handgunlaw.us

*New York and New Jersey are notable exceptions. Their mode of operation is to arrest first under state law, then let the courts and your lawyer sort it out.

And I don't understand that, why interstate travelers aren't "Federally" protected while in transit from one legal state to another. During my stint as a DOT weight inspector, I found many of the state commercial vehicle laws mirrored federal law and there where many instances where federal law stated what states could and could not do in regards to interstate commercial trucking regulation.

 

So, if I had the pistol unloaded and locked in a case in the truck of my car, where could the ammo be stored?

 

In a separate container (box); trunk is OK if the gun is locked in its own container. Again, the point is to prevent having a gun being available to shoot quickly.

 

When I had to go to Minnesota last spring, I unloaded the gun and locked it up. Gun in trunk, ammo in console.

Can't say I'm all that fond of the lack of reciprocity. No more Minnesota for me.
