Depends on the change. It would have to be very serious.
I live where I grew up, where my wife grew up, where my mother lives 25 minutes away and my sisters and brothers 90 minutes away. My house has doubled its value in 10 years, my kids are in a great school system, my town is safe, and I have a wide, wide, wide variety of handguns, rifles and shotguns to choose from even with the possibility of 10-round magazine limits and banning the sale of new ARs (existing ones grandfathered).
All in all, no, I wouldn't move.
Maybe it's me getting older. I'm moving farther away every day from "tactical" stuff and more toward timeless "classics" and "fun" guns (mostly 22s).
I want to teach my kids about shooting and hunting, not about hating their state/federal representative and fearing/planning to overthrow their democratically elected country (the best country on the Earth -- spend some time overseas then come back, you'll know what I mean.)
