The Vltor Fortis is a updated clone of the Bren Ten 10mm Auto pistol (Which itself was a CZ 75 clone). It was announced last year at SHOT. This year a final production model has been on display. It will be available in both 10mm AUTO and .45 ACP. It should be on sale later this year (2009).
You can follow the progress of the pistol at the Fortis blog.
