All of this mine bigger than yours kills me on these boards.
I look at man as a fairly week animal for the most part compared to other mammals.
While pheasant hunting I have seen a white tail with its front leg dangling with a second shot to abdomen with a 12ga. slug. Does that imply that 12ga slug is not a stopper. I think not. What this means is that shot placement and terminal blood loss is key to stopping.
Another example I saw Hunting show with a women on ESPN shoot a big buffalo with .375++ type rifle twice at less than 25 yards. That buffalo ran 50 something yards before dropping why is a big high powered rife not enough?
The simple reason is that terminal blood loss ( buffalo having more blood volume than man) had to be achieved before the brain was deprived of oxygen for the animal to lose consicousness and die.
Same is true for man except panic, pain, and fear are all a factors. Some people have low pain threshold and will say they are incapicitated with a sevre headache and some people have terminal bone cancer (very pain full death) and never complain or take a single pain pill. Same is true for bad guys some respond with rage to pain (FIGHT) and some with panic (flight).
Another major thought is that the need for larger more firearms has evovled from the use of illegal drugs and body armor. Lets face it if a bad guy is juiced up on coke you need a .357 , .40, and .45 (FBI incident in Miami).If a bad guys is wearing body armor he is prepared mentally for a fight and most handguns are completely in effective LAPD and bank robbery)
Now lets face it most bad guys are using a controlled substance ( small exception are the sexual predators ), and want an easy target to get what they need so they can buy more drugs these people are usually weak cowards when confronted; however, if they are in advanced stages of withdrawl they can become desperate and fearless. This why we should always prepare for the worst.
I personnaly carry a Smith J frame, I have a p7, P225, p226, and 1911. Why do carry a j frame because it is the easiest and best of both world .38+p hollow points, more reliable than mini auto (.25,.32 ACP, and .380). I can easily conceal in my pocket. It is all a comprise in our society due to the fact that we must conceal in order to not be considered a wacko. Now fantasize for a minute wouldn't it be great to live in the old west where you have a peace maker on your hip and grab your rifle off your horse as you walked into the saloon and nobody think anything about it .
