On the front of the grip there is a set screw that is called a mainspring screw in parts list page. It sticks out a little bit, you can sort of see it in the pictures. Is this supposed to be sticking out or should it be flush? I don't notice it when I shoot. I've tried turning it with a screw driver but it didn't seem to want to turn, I really didn't put much pressure on it in case I wasn't supposed to move it as I didn't want to damage anything.
