I carry one spare magazine, except when I am going down to the border, then I carry two--and I have an AR in the vehicle.
For ten years, I lived and worked on a ranch that had 25 miles of the international boundary as its southern border. I always had a 1911 or a Browning .40 on my belt, with two spare magazines on the other side. Never had to draw a gun on illegals, whether they were just walking or actually carrying contraband.
Nowadays, it's a different world.
