IMHO for my life to be threatened the person would have to be within 20 feet so I do not need anything that would be accurate beyond that.
For self-defense purposes, one should only ever discharge their firearm if the threat is within arms length (as a figurative term). Whether that is 5 feet or 20 feet is up to you. The point is that self-defense should not be a gun battle. If I'm by myself and there was a single threat, then I wouldn't be considering firing a shot beyond 10 feet. More than that, one could argue that I should have reasonable chance to flee. However, if I had one or two of my children with me, I'm not nearly as mobile so the range increases.
It is an extremely rare occurrence (so rare that you'd have to crawl the Internet to find more than a couple of cases) that a projectile discharged in self-defense strikes any unintended person(s).
