I am trying to educate myself regarding a type of ammo for a Daewoo DH40 THR. The ammunition in question is S&W .40 caliber frangible hollow point. My questions: 1) Are they truly good for home defense, 2) what is the nature of their 'destruction'? 3) When a person is shot with one, what is the intended outcome of the shot? I will PM anyone with need for more information. I am asking because I was shot with one in my own home 3 years ago, and forensics ruled the nature/behavior of the bullet as a freak occurrence. I am just trying to better understand.
