This mount fits (including but not limited to):
Firearms with a traditional Novak cut rear sight.

Please note, some manufacturers use licensed Novak rear sights. These are cut to the manufacturer's spec and are NOT GENUINE/traditional/true Novak rear sight cuts. One of the most common manufacturers to do this is Taurus. Ruger also uses smaller Novak rear sights on their fixed sight revolvers. Our mount will NOT fit these applications since they are not a traditional/true Novak cut. We do not offer any options for those applications. Please refer to Novak's Site and/or call the manufacturer of your firearm to confirm that you have a GENUINE Novak cut, not a licensed Novak cut.
Please See Our Common 1911 Dovetail Chart If You Are Not Sure Which Cut You Have
