Over the last six months, I have worked through a set of theories based on some discussions with some deeply experienced friends, which I would like to share. One high ranking Army friend—formerly a Night Stalker—said, “There is no one perfect small arm for any situation. The dynamics of the environment you expect to be engaged in dictate the armament.” For several reasons, it is my theory that an AR-15 pistol is the better personal defense and road travel firearm to have stowed in your vehicle.
