RE: dumbest question ever posted right here......
I have to agree with the others. Both my sidelocks, a Renegade and a Hawkins have the double triggers, and I use them all the time. When target shooting and hunting, as eldeguello said, once you learn them, that gun will fire and right now. When I am on a stand and I watch a nice deer headed towards me, I will often times, cock the rifle, and hit the set trigger. That way when I decide to shoot, that rifle is ready right now. As the others said, practice with them. Learn when they will fire, and how to un-cock the rifle as well, with the set trigger on. It is not hard to do. And once you are used to them you will wonder what you would do without them.
