Just bought a colt defender that comes with novak sights, thinking about putting night sights on it. Does anyone know if any 1911 night sights will fit or if it takes a special cut. I did a search on ebay for defender night sights and saw that a company meprolt makes a " true dot" but they are around 150 and that is a lot of coin for a product i know nothing about. Anyone have any experience with this night sight company or the colt defender?
