And when you have had your made to measure gun fitted remember it stays the same dimensions for the rest of its useful life unless you change it. But you as a living being will change over time usually putting on weight and the gun you had fitted when you where twenty something will not be as good a fit when you arrive at forty. So gun fitting is a continuous exercise unless you are one of those lucky people who can fit in to your wedding suit or dress for that matter some forty years after the event!!!!
