OK, 4 guns...
1) A 12ga pump with an extended magazine tube, peep sights, and mounted flashlght. A good big game weapon up close with slugs, small game with bird shot, and an excellent close range self defence weapon with buck shot.
2) A Ruger 10-22 rifle with a good scope, back up peep sights, and a box of spare magazines. Ultra reliable, parts and ammo available everywere. Perfect for gathering small game and birds of all types, and nothing to laugh at in skilled hands for self defence.
3) A Scope sighted Mauser or Remington bolt action with back up peep sights in 308 Win. Reliable, parts and ammo available everywere. Can be used to kill any animal at any reasonible range, and be used to keep 2 legged varmints at bay. A good military type semi-auto could be subsituted, but for really close up, un expected combat, the shotgun rules. Living to see another day is paramount, and at anything past shotgun ranges, you should be trying to get out of dodge...Not staying to fight a rifle range firefight.
4) A Glock #19. Again, reliable, common and effective ammo available. To be kept on ones person, along with 2 spare mags, at ALL TIMES. Forget about handgun hunting, thats what the other stuff is better suited for, this is your last ditch save your bacon tool when things suddenly and without notice, go bad.
I would be sure to stock up on spare parts, magazines, and plenty of ammo for each of the above. A good night vision scope, and binoc's would also be of great value..
