Hollow Points VS FMJ
I use Speer Gold Dot 55gr. .40S&W identical to what SAPD carries. I know what FMJ means in a long gun round but I'm not sure what would be in a handgun round. I do know that I want maximum stopping power and minimum chance of "over penetrating" - i.e. through-and-through. Through-and-through is bad from two standpoints. First if the projectile exits the tango then there is energy on the projectile that did not get transferred to said tango. Second, if the projectile exits the tango then it could hit an innocent bystander on the otherside of the tango which could easily result in TWO people taking you to court. Since I have allegedly had special training (like LEOs and CHL licens holders) I would face a stricter standard than some joe blow off the street.
I do know I have a tiny advantage regarding intent. Should I wind up in court, I would call the man who trained me when I took the course to get my commission as a wittness. He would testify that I was taught to shoot to stop rather than to kill. I was still trained to aim for COM but the goal is to stop not kill.
BTW, a .40 cal JHP is not always or even often lethal. All the more so if the tango is hopped up on drugs and/or alcohol. There was a guy went postal at a Dennies a couple of years back. Killed on cop and wounded a couple more. He got something like 5 of those Gold Dot .40s and lived to go to court. I am happy to say he got LWOPP and so will be a guest of the taxpayers of Texas until he dies.
Jorg, Coronach, the meaning of the "better 12 than 6" saying is simply that it is better to live through the incident. Your "slippery slope" is the result of taking the saying beyond its intent and meaning.
My maxim is a bit different. You can be paroled from prison. There IS no parole from the cemetary. I have no desire to kill anyone. But if the situation is such that someone's wife is going to collect their hubby's life ensurance, then I am going to do my best to see it isn't mine.
