Yeah, but not only that, the gun is cocked isn´t it? I guess that picture, while being a "still", can be of Bond cocking the gun and taking aim...so the "high port" position could maybe not be a position at all but part of an arm movement. I know, I know, grasping at straws here.
If you are going to shoot someone you do not have your finger on the trigger in the "High Port" position. Period.
As you bring down your weapon you than move your finger to the trigger, pick up your sights, and fire (by squeezing the trigger) if the threat is still presentable.
Many posters and book covers probably show Bond with his finger on the trigger and any 80's action movie will too. In today's movies I would hope the military advisors would get it right.
Would you cock a weapon with your finger on the trigger?
