when i pull my bow back it pulls like it wants to fire i noticed some bows have i guess its called letoff and when u pull it back u can almost let ur arm relax and u dont struggle to hold it how could i adjust my letoff ?

Your bow probably has too long of a draw length for you. You may not be reaching the let off.Take it to an Archery Pro Shop (Not Bass Pro or Cabelas)and have them check your draw length and then check the bow.

Im FAR from an expert but I agree with jmbuckhunter that your draw length isnt allowing you to get to the let off

nah i dont think its to long i oull it back as far as i can but i will take it to a pro shop thanks
