I don’t have a formula for capacity. I just pick a CCW gun for handling, shooting, concealment, and presentation characteristics. My main gun has a magazine capacity of 10. (Sig P365 just edged out the Glock 26.) My sometimes backup/occasional primary pocket Glock 42 has a magazine capacity of 6. I carry 2 spares for both. If I have to go against 3 people by myself with my family behind me, the calculus for survival likely is going to depend on a lot of footwork and aggressive initiative along with some reloading. I once had to pre-plan my way through a situation like that with a S&W 640 and a couple of speed strips in my front pockets. (Fortunately, I never had to test the plan.) The guns available to me now are much better than that!
