Hi, I have not yet been able to put any 9mm ammo in my gun. STill waiting for a shipmetn in the mail. I notice when I rack the slide of my SIg the hammer will go back. However, when I try to decock the hammer using the decocking hammer it doesn't work. I am wondering, will the decocking hammer only decock the hammer if their is a bullet in the chamber? I thought it would work regardless if it was loaded or not. I want to make sure there is not a malfunction with my new gun. I am not able to read anything in SIg's manual about this. Gotta wait few days before my ammo arrives
