If your revolver is not drilled and tapped this mount will not work. The best way to verify that it is/is not drilled and tapped is to open the cylinder and check the rib underneath. There should be through holes that are drilled and tapped. If there are not (like the above image) this mount will not work without you having the gun drilled and tapped. You can have a competent and qualified gunsmith drill and tap the top strap with the standard S&W hole pattern which will allow you to use our mount.
