The Trijicon RMR mount with integrated Night Sights is designed specifically for the 1911 or 2011 platform handguns. This mount requires a professional gunsmith in order to complete the installation. The mount will require your slide to be machined in order to properly mount.
Important Note: The 1911 RMR mount with integrated back up iron sight is a fixed rear sight solution. To achieve windage adjustments for point of aim (POA) point of impact (POI) the gunsmith must drift the front sight left or right. Move the front sight in the opposite direction you wish the point of impact to move.

If adequate height relationship cannot be achieved by changing milling depth, alternate height front sights are sold separately.
