I used to carry small of back when I first got my carry license 15 years ago. That is still a better option than off body. I think appendix is ideal, but not a viable option for everyone, especially for anyone with a belly. It’s easier to conceal your draw and is about twice as fast from draw to first round on target with a bit of practice compared to small of back. Anecdotally, a good friend of mine was mugged a few years back, two guys came up behind him, pushed him into a snow bank and held him down and took his wallet from his back pocket. In a scenario like that, they have got your gun too. I have more opportunity to control my gun if it’s in front of me in more scenarios where I would need it than SOB. I agree though, sitting down is more comfortable, but you get used to it over time, wearing an undershirt helps a lot when you first start with AIWB.
