You own you would go to if SHTF. Discounting reliability, I don't own any guns that aren't reliable. I'm thinking my single six. 6 shots of .22 out of a pistol is not going to accomplish much. Great gun for plinking but way to many other options. If I limit my choice to centerfire, probably my P64. Again, capacity would be the issue plus slow mag changes with the euro style mag release. Plus its only good for very short range with the tiny little sights. Rifle, I'd leave the mosin nagant in The safe. To heavy to carry around, ammo hard to find and I can't hit squat with it. Big heavy tough round though.
