Not sure this has been answered - but do you know whether you want to learn how to shoot for practical knowledge purposes or do you have other goals, like home defense?

If home defense, I'd strongly suggest taking a full pistol course. To be completely honest, in most urban/suburban settings - your best plan is to just get out of the house unless you are regularly training with your pistol and have the trained, controlled response you need so you don't accidently plug your SO, kid or (heavens forbid) a dog whilst trying to protect them.

If practical - dude, there are few things as fun as going and pinging .22lr rifles...the ammo and the guns are super cheap. Except in close range personal protection, the rifle is also going to solve your "what if I need to shoot food/zombies" late night worries...with far more accuracy and range. The AR-15 is actually a great all-round rifle to have in your safe.

My suggestion is to take a course from a professional. Do a safety course. You've been given a number of options. Then decide what you want to do from there.

Buy a safe before you buy a gun.

*Ensure you have a close friend who you can talk to if you need to not have your guns for a while, and you have another location to store them in case you ever don't feel safe having them for a time.*

Guns are fun, and one of our great liberties - from a one lefty to another - enjoy!
