With the exception of those that will say the best place to put a firearm is on your person (with good reason), where or how do you carry your defense firearm in your vehicle?
I have a paddle holster rigged to the door pocket of my drivers door. I can just reach down and immediately have it in my hand. Only problem with that is it's clearly visible when I open the door. Been meaning to rig up a flap to cover it but haven't gotten around to that.
