If you had to choose only one gun for the rest of your life, no limitations except the destruction of every other firearm you have. What one gun would you keep, or aquire? Just humor the thread nay-sayers!
Mine: Rem 870
With 2 barrels this gun provides food, and protection. Can do the same with just 1 barrel!
Ok if ammo is not an issue I would choose my Shotgun If all the ammo was also going to be gone like I had to store ammo for the rest of my life then a 10/22....
