Quick update from the original questioner:
Thanks again for all the great advice! I did a few sessions at the range this winter, and recently purchased my first handgun – a Springfield 9mm XD.
I would have preferred to start with a .22, but the ammo situation there looks grim now and into the future for it to be my primary handgun. And, I now know from my time at the range that shooting the 9mm is really fun! Now that I’m set with the 9mm, I feel like I still want to get a .22 as a bonus, and shoot that whenever I can find ammo.
Permit to Carry class is next, although, right now, the 9mm feels huge – I can’t imagine being able to conceal it. Hopefully, that will change as I get more used to it.
Best to all!
