Yeah, I agree for sure, on the rifle round being more effective than a 9mm in the absolute........................but since 99% of those carrying daily are using handguns, I think we can surmise that the handgun round is "sufficient" for the most part, whatever that means, for short term, short range encounters.
If I know or think something more than that is going to be on the menu, then I'm going to pick a longer gun anyway.
So for me, average Joe Schmo, the 10.5" AR just doesn't have much real appeal, other than a novelty, hence the right bullet for it is kind moot.
And so I just use in my 14.7" gun, what I use in my 16 & 18" guns & don't give it much worry.
