One really good thing you mentioned was "Put it in a pouch, even if it's in a pocket." with reference to reloads.
A few things I think could be improved:
Complete neglect of the "pocket carry" method used by a high percentage of carriers (both civilian and LEO).
500 lumens is too bright for nighttime indoor operations where you could be blinded by your own light reflecting off mirrors, windows, even white gloss walls.
OWB holsters with hammer retaining straps and exposed triggers are perfectly fine for hammered revolvers and hammered DA/SA autos carried fully decocked.
