As usual I need educating. Have not looked at this gun. Would like some input before I do next week. This is supposedly a fairly new 20 double with 12 inch barrels from the factory. It only has one trigger? No selector, it fires one barrel and then the other. This gun has external hammers. All the muzzle loader doubles I have looked at had a trigger for each hammer. Is this a real factory setup with short barrels and only one trigger? I was hoping for a handgun but he said it has a straight grip stock. I am totally ignorant on this one. Any one know anything about this type gun and value?
