With the release of the new Aimpoint COA again ICM is pushing the limits and offering the cut for 1911/2011 slides. This can be done on slides with standard iron sight cuts and Novak style cuts. We are working on the Bomar cut slides now and will have a solution soon.
This includes the cut and the retaining piece. We use 4mm screws for the retaining piece and those screws are also included.
