Wow! Where does this come from? Do you realize that the people to whom you speak have more experience in their little finger than you do in your entire body? I thought recently you may be coming around but it turns out you are unteachable. I've seen that plenty. Whatever. Your poor, misinformed choices don't affect me or mine. This just continues to be laborious and you are obtuse. Such as: 1) What is your definition of "performance" and what is not being understood? 2) The 9mm is being claimed by you by others to be just as good as what compared to what? Sadly, you're still fixated on energy and the Laws of Physics, both topics you know nothing about. It's painfully obvious you have zero understanding on how bullets wound and even less knowledge on a bullet's interaction with tissue. ZERO. You still have not answered why you recommend heavier, larger caliber bullets for tougher creatures even though they have less energy. Again, intellectual dishonesty on your behalf. Why don't you carry Glaser? Immediate and total energy dump! Violent explosion of the projectile! High performance! Physics in action! Why do you choose slow-to-dump hollow points when you know how important energy dump is? Calling us trolls which you yourself have become? That’s rich. Why don't you teach us misguided children on the concept of energy? We obviously do not understand and for you it is basic. What is it you understand that we don't? Please be detailed in your explanation for clarity. A revelation in terminal ballistics would be an exciting topic of conversation. And don't accuse me of being a closet 9mm fanboy! I own five handguns in that caliber. I carry one every day.
