Yeah, it's changed a few things for me, but I seem to be going against the current.
I'm no longer occasionally dabbling in semi-autos. I'm back to magnum revolvers (usually an S&W 65, 28, or 629). If civil unrest causes me to have to defend myself, I want the most reliability I can get. While I don't rely on the concept of stopping power, I'm sticking with calibers that give me a better chance at resolving the issue with the least number of shots fired.
I'm also keeping a long gun handy. For reasons stated above, the long guns I keep accessible are 12 gauge shotguns.
Another plus for magnum revolvers is that, as a handloader, I can always find cast lead bullets for lots and lots of practice. Finding plated or jacketed bullets for polygonal semi-auto barrels is getting more difficult every day right now.
But, more than anything above, I pay very close attention to the news now, trying to anticipate what problems are brewing near me, so I can avoid those problems entirely.
