Everyone not on the Internet knows that 9MM is just as good as .40 or 357 Sig

Even I know that 9MM is just as good as .40 or 357 Sig

I just don't believe it.

Claiming to know something and truly believing it is a problem for many people about many things.

I myself try to avoid claiming to know things that I don’t believe, and I don’t believe that less power is as useful as more power when work (e.g., terminal ballistics) needs to be done. I just don’t try to change any minds because as I often state, if I am ever shot I hope it is by someone who believes less power is just as good as more power.
