One Handgun, One Rifle, One Shotgun. You are able to choose just one of each for self defense with NO modifications.
Handgun: Sig Sauer P226, in 40 S & W, with a light rail and night sights.
Shotgun: Remington 870, 12 gauge, 20 inch barrel, rifle sights.
Rifle: 16" AR, with A2 buttstock, you know, so I can hit people with it.
There you go, nothing fancy, just three firearms. Also please note that my Bug Out Guns are a little different than this list. Hmmm, I may resurrect that tired old list tomorrow.
