likely only the pull weight will be able to be adjusted(with gun out of stock, and upside down, there are two screws on front of trigger assembly, pull weight is top screw). The new epoxy remington uses is crazy. To do a "proper" job all three screws should be adjusted. Use a scale to check that the trigger pull weight is consistent(I use a rapala digital fish scale), and make sure to go through the steps to make sure the sear won't accidently slip(slam bolt a bunh of times, engage/disengage safety, etc)!
Using only the weight adjustment I got my 700P to 2lbs10ozs safely.
