If I was in a survival situation, the one firearm I would want with me would be a 12 Gauge Shotgun. I'm NOT talking combat here, but harvesting food. With the ammunition availble today, you can carry in your pockets the proper loads for feathered game, small game, waterfowl, or deer sized game. I can't imagine a survival situation where the shotgun wouldn't be the most useful tool you could have. Terrain varies, admittedly, but in my area, and other areas I frequent, I certainly could feed myself with game I harvested with a shotgun.
