Mind if I ask what you chose? I'm studying a couple different methods, but chances are I'll end up using one of my guns to ctb (either my rifle or handgun).
I went with a .45 acp pistol. There's no way i'm surviving that if I shoot within an inch of any of my vital organs as long as I make sure there's no one close by to "rescue" me when they hear the gunshot, especially if I use jhp which I will.
I'm happy for you to find your way out!! I think that's one of the hardest steps for people who want to CTB. As someone who is also looking into purchasing a gun in the US, what kind of form did they make you fill out? I'm going to be getting my driver's license soon and doing research on the process.
It's gonna depend on the state and local laws where you live but all I had to do once I met up with my ffl dealer to do the transfer was fill out the ffl transfer form which just asked for standard info like name, address, etc. as well as a questionnaire with typical background questions like criminal history, citizenship status, etc. Basically, as long as you've never been convicted of a crime, have never been forcefully institutionalized, and are a US citizen, it should be piss easy to get your hands on a gun where I live in the US as long as you're of age. I should probably note that you'll only be able to get a handgun this way like I did if you're at least 21 in most places in the US and for a rifle or shotgun, at least 18 years old. This'll depend on the gun laws where you live, though, so I would look into those if I were you.
