    The FBI mininmum penetration test of 12" in ballistic gelatin for defensive handgun calibers is always a good start when selecting your carry round. I carry 147 gr standard pressure JHP's in my carry 9mm's, 180gr JHP's in my Glock 23, and 230 gr JHP's in .45acp. For the Glock 32 and 33 in .357SIG, its Hornady TAP 147gr JHP @1250 fps.....which probably would be completely off the picture below.

    FBI Report on Shooting

    I've attached a FBI follow up report on a shooting. 3 Officers and 1 Bad Guy. Bad Guy a 45acp, Officers used 40 S & W and .223/5.56. As this shows placement is everything!

    I am a retired LEO. I was on the job for 32 years. If I had a dollar for everyone I saw shot to death with just a .380 I could buy a nice steak dinner.

    I absolutely believe that as i have done some pumpkin shots and water jug test and boy does the .380 have power out a 2.7 inch barrel and even more out a longer barrel. That is why i choose to EDC my P238, i put another 100 rounds through it remington 88gr HP ammo and she swallowed them whole without any issue

    In terms of energy, velocity matters a whole lot more than size of the projectile. energy=1/2(mass*velocity^2)

    so speaking in .380 terms you would go with a higher velocity bullet vs a heavier bullet? Many people say to use FMJ for penetration because HP will not expand reliably but i will continue to carry my HCD ammo and hopefully not have to find out if it does....

    True, but not when you add the hollow point to the equation....

    It dumps a large amount of it's energy on impact, unless it gets clogged that is..

    then you must have been totally comfortable carrying a .380ACP as your primary duty weapon, right?

    Yes, but since higher kinetic energy is only loosely related to real-world effectiveness...

    Here is my two cents. In most civilian concealed carry events out in public a 9mm with a quality hollow point is a great round for self defense. I look at shooting situations for civilian concealed carriers in two parts. First is shot place, 2 x 124 grain hollow points entering a person's chest through the sternum do the trick. As for the "ONE SHOT STOP" it doesn't matter anyway, most every shooting I've ever heard of has multiple shots being fired. More times than not a person is going to fire more than one shot simply due to stress and being in the heat of the moment, and that will bring ones training into perspective as to how well they can do follow up shots under extreme stress. Second is going to be tactics. Saying that you made your good shots on the bad person, a person is going to have two choices 1 is to break contact and move to a position that will give them a better advantage on the BG or 2 is to close with the BG and continue to engage until there is no more threat. With good shooting, strong tactics and a whole lot of luck one should survive a potential lethal encounter.

    As to the overall stopping power of a particular round, I think there are way too many variables that come into play for example the makeup of the person, are they on some sort of mind altering substance, how determined they are to fight and such. I personally saw a suicide bomber in Afghanistan take two rounds to the chest from a M240B and three rounds from a M4. He was still able to get up and move close enough to blow himself up and injure 3 US Soldiers.

    there was a study done by medical examiner that basically says that any caliber can do you in, the difference is shot placement and how quickly the person goes down and bleeds out. a .22 can kill you just like a .45 can, but the .45 would probably cause more trauma resulting in a quicker death

    I don't think a medical examiners point of view on how efficient a particular round is in killing someone and how fast has any baring on how effective a 9mm round is. I don't think that self defense with any sort of weapon is about killing someone else. When you are talking about using a tool such as a gun or knife or other deadly object in protecting ones self, someone is likely going to either be killed or seriously injured. Stopping a treat against your life can mean anything from posturing yourself to show the BG that you can protect yourself to firing possible lethal shots.
