Jfrancis, there really isn't a "standard" dovetail for the 1911. The dovetail for the front sight is cut to accomodate the sight manufacturers choice in angle, depth and width. A lot of smiths will install a fiber optic insert in your front sight. I do it in my shop. I charge $25.00 and I think I'm about average on that so I would expect that's about what it would cost you to have it done. George
