I have a very light 5 1/4 lb. 20 ga Fox and i milled some weight off the inside of the trigger plate. Filling the sides of the frame to remove sterlingworth on sides of a project gun i am building took a good bit of weight off frame .Have no idea how much though.You can round the nose of the frame and forend iron to remove more. Wood density and barrel weight usually contribute most to total weight of gun .On sterlingworth extractor forend you can mill weight off under the long forward tang part.Bobby
