I just bought a new silver pigeon s and want to add 18 oz. in total. 9 oz. in the stock is no problem. However I'm unsure how to add the other 9 oz in the front. I thought about a clamp on barell weight but want to try to avoid that as I love the way the gun looks. There is a little room along side the middle rib between the rib and the forend where I thought I could slip in a little lead but I don't think there is enough room. How would you guys add the 9 oz. in the forend. I would really appreciate your help.
