gun wont fire

Question
I have a jennings nine and all of a sudden it just won't fire. what should or can I do to fix the problem

Answer
As I stated in my last message, there are a lot of factors to consider, load, bullet brand, maintenance of the weapon, noumber of rounds fired in weapon (weapon Life).  I would take it to a good gunsmith and have it looked at, he/she will not charge you until they determine what the problem is
