Downsides of the gas operated mechanism are the colossal bigness of the Desert Eagle, and the fact that it discourages the use of unjacketed front rank bullets, as lead particles sheared off during firing could clog the gas release tap, preventing proper function.

The most recent model, The Impression XIX, is at hand in .357 Magnum, .44 Magnum, and .50 Action Express (or .50 AE). This model comes in a variety of at variance finishes, such as brushed Desert Eagle chrome or titanium gold. 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 and the .440 seems to have gone the way of the .41 Magnum. Mark XIX barrels are on hand in 6 and 10 inch lengths only.
