What are you talking about[in saying that averages do not matter]?
One of the claims most often heard in discussions about defensive shootings , goes something like "the average gunfight is over in N rounds", where N may be 3, 4, or 5. That is often used to justify the belief that a handgun containing only a few rounds would be all that a defender should need for primary carry.
One problem averages is that there have been many incidents--perhaps half of the total--in which the average number, whatever it may be, would not have enabled success. That's why averages are averages.
On would need to know more than the average.
If we had the data--and we do not--we would have to consider the extreme values that have occurred, and the frequency distribution around the average.
Even then, because of the small number of actual defensive shooting incidents, we would not be wise to place much confidence in the actual data.
The average gunfight. FBI stats say the average is 3 shots, 3 yards, 3 seconds.

That has been posted before and discussed here at great length. The source has never been identified or validated.
I care insofar as I don't want to be involved in a potential serious legal entanglement.
The demise of a person or the lack of it will likely not affect that. Threaten deadly force or use it, and one may well be in grave legal difficulty.
Why don't you put your money where your mouth is and stand in front of me shooting my 'cap gun'?
That is among thr dumbest of the arguments that are occasionally voiced here.
Except you haven't shown any evidence that a .380 will result in my funeral.
One can say nothing about what
will result in the use of any firearm.
The scarcity of actual date, in comparison with the number of variables involved, is such that
how likely an out come may be cannot be determined using actual data.
Scieitific data such as the forensic medical analysis used in the report
Handgun Wounding Mechanics and Effectiveness, from the FBI Training Academy at Quantico, VA, when combined with extensive lab testing in surrogate test media, can help.
They recommend the 9mm with certain ammunition. They do not as yet recommend any .380 rounds.
The 9mm may fail, and the .380 may sometime succeed.
The 9mm is a better bet.
I prefer to have more margin.
