This sight is designed to replace the old-style square-tang sights with the small attaching screw found on older Smith & Wesson revolvers.
These sights must be drilled for the attachment screw by you or your gunsmith. This service is available from Bowen Classic Arms for an additional $45.00, but we must have your original sight or measurements of the screw hole layout. Please call (865) 981-8869 for assistance. These measurements vary from model to model and often gun to gun. Please note, once the hole has been drill in this sight the product is non-returnable. Also, To find the appropriate blade height please consult the S&W blade height chart.
Please read the tech notes for more details.
