Since Trump's election, gun groups catering to progressives and people of color report a surge in interest as they look to defend themselves in a country that, to them, feels increasingly unstable.
For almost my entire life, I never thought I'd own a gun. Now I do. You definitely need to practice with it at a range of your choosing, and keep practicing. I didn't start carrying until after I'd been to the range a dozen times. I still don't carry every time I go out. I don't pretend to be any kind of expert, but I'm happy to talk about what I do know if ever you're interested.
Something I've noticed: carrying makes me extremely polite. Because if I have to draw, I need to already have been doing everything right, or I'm going to prison. Even if I'm totally in the right, don't even get charged with anything, the aftermath of such a situation would be life-changing, in a very bad way. There is no good outcome to an imminent threat to life or limb; being armed gives me the chance of choosing the least bad one.
