WHAT IS THE BEST CHOKE FOR USING HEVI SHOT WITH A NOVA. WILL BE USING HEVI SHOT 3 INCH # 4'S

I AM HAVING A PROBLEM WITH A PIN IN MY NOVA. IF YOU HAVE A NOVA MANUEL, IT IS ON PAGE 38 AND THE CODE NUMBER IS 047N. I AM HAVING A PROBLEM WITH THE PIN STAYING WHERE IT IS SUPPOSED TO STAY. IT SEEMS AS IF IT WOULD FUNCTION FINE WITHOUT IT, BUT I AM NOT SURE. WHAT IS THE FUNCTION OF IT, HOW DO I GET IT TO STAY IN PLACE, AND DOES IT FUNCTION FINE WITHOUT IT? AND FEEDBACK WILL BE GREATLY APPRECIATED
