Placing the trigger finger out straight along side a firearm is necessary In safe handling of any of any firearm. We should train ourselves to keep the index finger straight when the front sight is not on target. With the proliferation of semi auto the trigger is usually lighter than the double actions of years ago. This lighter pull of the trigger is lighter and easier than a double action and therefore easier to shoot. Keeping the finger out of the trigger gaurd and along side the frame keeps us and our families safe.
