How to Mimize Lethal or Egregious Bodily Harm

There is no correct answer for that. Sometimes the answer to mitigate lethal or egregious bodily harm is not a firearm at all. Firearms are applicable in an extraordinarily narrow range of scenarios, but those range of scenarios are catastrophic and need extreme measures to be mitigated. So it depends on what, if you are considering bringing a firearm, what is the fire i'm good at? And then you get into the minutia of what firearms good for what thing, which depends on your legal context and particular threat.
