Though some decry the caliber as being too weak for social use, I feel if you do your part and place the bullets where they belong, it will do just fine.
Some decry it BECAUSE it's too weak for social (anti-social?) use.
If it were enough, then cops, soldiers and others would select it first, citing high capacity and ease of shot placement. Such is not the case.
Jeff Cooper was once called to testify on behalf of someone that used a Beretta Model 84 (13+1 .380) to show how fast firing 4 rounds could be done. This point of the case wasn't that the defendant had to shoot the miscreant, but that he shot him "so many times." Clearly, they opined, that anyone hit with one or two shots would immediately stop doing the act for which he was being shot, so any additional shots after that would not be needed, and, therefore, constituted that the defendant then had "murder on his mind" instead of simply firing to stop the threat.
For the "placement is everything" crowd, if it were easy to execute perfect placement in a life or death situation, then everyone would be carrying .22 rimfires.
Granted, a .22 longrifle in the eye at 10 feet should be expected to kill the badguy just as dead as a .44 magnum in the eye. Dead is dead, after all. But while the smaller and less powerful calibers nearly require surgical placement, the larger calibers give you some leeway (to an extent) Keep in mind, you're trying to hit the guy while he is trying to kill YOU. This may disrupt your surgical precision somewhat, in spite of how good you are at the range.
And before someone says, "The Israeli Mossad agents use the .22 rimfire for assassinations..." there is a big difference between going up behind someone and firing a few rounds behind his ear from mere inches away to reacting to someone trying to kill you and being able to hit his eye socket
before he succeeds in killing you.
There are 3 reasons to carry a .380 on purpose for defense:
1) It's the largest caliber you can control.
2) It's the largest caliber the govt will let you own/use for defense.
3) It's backing up your
real gun. (9x19mm on up)
