Everyone should take research design in college or they should teach it in high school.
I was an expert on a case where a big guy had a paring knife stuck in his chest and he dropped stone cold dead almost instantly - carry a paring knife.
Completely true, and I'd never argue it. I'd be very confident with a 9mm or a .45 too. It does get tiresome though, as a .40 fan, to read about how .40 is hard to handle and/or superfluous, I shoot .40 better than 9 out of the same platform. It doesn't make sense and shouldn't be that way but it is.
Choose what you like. None of them are "useless".
