I am 71 and not in the best of health. I also live way out in the country. I have no intention of leaving my home even in the event that some ferals make it this far out.
Now if I were warned beforehand, I would certainly think about sitting in the woods and keep a watch on the house but only for short periods. At night I would depend on my mutt giving warning.
I hear ya. I’m almost 70 myself and a mere shadow of who I was at 50.
I don’t just live way out in the country though. I live on an island in SE Alaska. While my fantastical imagination can conjure up a scenario wherein evil “Smokers” from Seattle attack the island on soot belching jet skis or Nork Commandos parachute in to secure the strategic salmon hatchery nearby and I’ll need fully automatic crew served weapons (Which I will fire from the hip, John Wayne style) to repel the invasion, it’s really not likely.
What I will need a gun for is hunting for the pot and bear defense. If it will do that it will be adequate in the unlikely event that two legged predators have to be dealt with. I’m fine with an 18”bbl, 12 gage pump gun in just about any situation for which I might need a fire arm.
