Recently I started thinking of the best option for a weapon that I can carry in a BOB and or a car when traveling. I love guns, think every good citizen should own one but I think that something simple like a pistol will be fine for my needs. It's easy to conceal, doesn't standout and can be very lethal with training. Home isn't a problem but if some disaster happens and I am in another town or working and I can't quickly get home I feel that it would be a good idea to have some form of protection. Currently I have two .40 pistols, a Glock .22 and a compact .40. I may end up buying something for the BOB/Car because I keep the other two situated at home in two locations for home defense. I was thinking about getting another .40 since I already have two and I only need to buy one ammo type for all three guns, but a 9mm would be lighter and could carry a little more ammo, I would probably only take a mag in the gun and 2 or 3 spare mags. Then I could go with something like a .357 that would have less ammo but good power and penetration compared to the others. Having a few pistols in different calibers may be good if The poo really hits the fan and things change forever. About 95% of my survival planning thought goes into stuff like food, equipment, tools etc. In your opinions what do you think, what do you plan for in your BOB/Car setup? Am I over thinking it, under thinking it?
