Evidently, I have been wrong.
I don’t have enough ammo.
A CCW pistol will be of little use against violent mobs blocking highways. I advocate a car or truck rifle. My preference is a AK-47 with a green grocery bag full of loaded magazines. The AK is not a rifle I have emotions for, not like an M1 Garand. If it got stolen from the car it is the gun I have the lowest emotional attachment for. But for reliability and capacity it is the perfect communist weapon to turn around on our new communists.
