A two stage trigger requires the shooter to take up slack in the first stage of pulling the trigger and then apply slightly more pressure to the final process of releasing the sear. In the…

A series of gradually increasing amounts of pressure are applied to the trigger point by the massage therapist until it 'dissolves' and then stretching is used to help flush the…
