The best way that I've found to approach this situation is as follows:
1) Remember that none of us on here are Lawyers and can not give you actual legal advice. "But MrCoolDale on DelOC.org said..." means nothing in court. Please consult a lawyer.
2) You may not conceal a firearm, no matter what state it is in (disassembled, unloaded, etc) on your person without a CCDW. If the firearm is in plain view, it may be loaded, cocked, locked, ready to rock. I strongly suggest an outside the waistband holster (commonly referred to as OWB) with good retention. Serpa holsters seem to be among the favorite choices.
3) In your vehicle you may have a loaded firearm in plain view. Many here suggest on your dash, attached to your seatbelt, on the center console, or even on your passenger seat. You may not conceal the firearm inside your vehicle without a CCDW. The exception being the normal laws applying to transporting a firearm. Keep your firearm and ammunition in SEPARATE LOCKING COMPARTMENTS, not readily accessible to the drive or other passengers. I usually stow the firearm in the trunk and the ammunition on the backseat. I have also gone the extra mile to bolt a small safe into the trunk of my car.
Above all, don't try to be clever. Once you start using technicalities you are asking for trouble. Keep it simple and don't get yourself into trouble. Technically, your glove box and center console are separate locking compartments. With the glove box locked, that wouldn't be readily accessible. Sure, that may have some merit, but I don't want to argue it in court.
If you have an SUV or a truck, whereas the storage area is not a separate compartment from the passenger area, I suggest bolting a small safe into the rearmost position of the vehicle. Small pistol safes can be found for fairly cheap and they are a worthwhile investment.
The goal is to keep your firearm safe from anyone who may try to break into your vehicle.
Basic Gun Safety by Jeff Cooper:
1) All guns are always loaded
2) Never let the muzzle cover anything you aren't willing to destroy
3) Keep your finger off the trigger until your sights are on the target
4) Be sure of your target and what is beyond it
