That sounds like a "best option" scenario and were I in your position -- sounds like something I might do, too.
However... we really *ARE* discussing the differences between Mark II's and III's here, as Ruger has changed them. Can we agree that Ruger cut an ugly, oblong HOLE in the side of our favorite pistols and to correct that, you've got to contact Mr. Patza to attempt to rectify what they've done?
