I'm new to this website but was referred to it by a friend who has found it very helpful and informative. I recently purchased a S&W MP Shield 9mm and have found the trigger pull to be very heavy. I purchased a tool to measure the weight and at its max pull weight(10 lbs) the tool couldn't get the gun to discharge. I live near Westborough Ma and am trying to find out if there is a professional nearby who can lighten the pull.
