Legally, it looks to be pretty much by the book. Even shooting while escaping (normally a no-no) is probably legit, here, since the bad guys still had a deadly weapon. He even had a reasonably clear background.
Might want to get-in some more range time, though. (Heck, we all should.) Still, shootin’ under up-close-and-personal pressure is hard to do perfectly, unless you train daily.
I like how he waited until the perp wasn’t looking before he drew. You can’t out-draw a drawn gun, so you need movement, distraction, or aggression (see: previous lecture on OODA).
Train yourself to do a double-tap, though. Don’t wait to see if the first shot hits.
Try to keep your more-accurate two-handed grip, too; although I suspect moving balance was an issue, here.
The .380? Wellp … he had it on him, the good guys lived, and the bad guys left, so it was good enough.
Heck, that’s what I carry in very-polite society (Colt Mustang Pocketlite), but a .357/.40/.45 in injun’ country.
All in all … attaboy !
