I'm no expert, but I know the people I know who shoot da/sa guns say the same thing - get sights on target, pull trigger. In that order. Probably some bad shooters with da/sa guns try to get on the trigger early because they have weak hands or they have bad habits or whatever. I can't really comment on that.
However, I think we can all agree that getting on the trigger before the sights are on the target is doing it wrong. Unless someone wants to argue for it I don't think it's a point of discussion any longer.
