Look at Colonel Drydock run that rawboned 100 year old Colt!
He's in the middle of taking a shot double action-hammer is on it's way back-left hand pointer finger wedged under that trigger guard for support and stability through that long hard DA trigger pull.
I don't recall seeing him miss any of the DA shots, even the long ones, so he must know a thing or two about runnin trigger cocking pistols!
