You should feel a difference but there will still be resistance there when you pull the trigger. A change of a couple pounds in a trigger spring makes big difference.
Can you squeeze both springs when they are out of the gun and feel a difference? When I get home I can take mine apart see what I can feel.
If the pain is lacking so is the discipline...
