Pieper used damascus because it was cheaper for him in the 1880's. Also, damascus has a beauty of it's own. Others used fluid steel barrels.
Any how, I am just trying to show you even more options for your search. I have hammer guns in most gauges. They are fun to use. They do require different gun handling to keep things safe. It is very common, for instance to cock both hammers when a bird rises. Hit the bird and you must remember to lower the second hammer. When decocking a hammer, always point the gun in a safe direction.
Enjoy the search. I will be curious to see what you finally choose. There are a lot of choices, both modern and vintage. Some are very utilitarian, others are works of art.
You could even go to a drilling...
