Three different versions of the Desert Eagle were manufactured: the Mark I, Mark VII, and Mark XIX. The Mark I is no longer produced, but had an aluminum frame that was available in .357 Magnum and .44 Magnum. The Mark VII was built on a steel frame and was available in .44 Magnum, .357 Magnum and .41 Magnum chamberings. The Mark VII is out of production, but the manufacturer still has 6 and 10 inch barrelled .44 Magnum Mark VIIs in stock (early 2005). The most recent, the Mark XIX, is available in .357 Magnum, .44 Magnum, and .50 Action Express (or .50 AE). Magnum Research also showed some models in .440 Cor-Bon caliber, a .50 AE derived case, but no .440 Cor-Bon components are listed in their catalog.
