I called a local gunsmith here in Idaho. He told me it would run $145 to drill and tap. That seems crazy to me. What is the going rate? What I should do is drill and tap the cd youth model. The very best pattern I've ever shot came out of that tiny gun. I've always hated this Benelli. But its paid for and it's what my son shoots at ducks. Now he's wanting to carry it for turkeys. The poi is super high on it. So we're going to have to do something if he's going to use it.
