The Desert Eagle is fed with a detachable box magazine. Magazine capacity is 9 rounds in .357 Magnum, 8 protection in .44 Magnum, and 7 way in .50 AE. The Desert Eagle's vat features polygonal rifling. The submachine gun is mainly nearly new for sport, use shooting, and hunting.
The Mark I, no more produced, was offered with a steel, stainless gird or aluminum alloy frame and differs primarily in the caliber and shape of the freedom levers and skate Desert Eagle catch. The Mark VII includes an adjustable trigger (retrofittable to Mark I pistols). The Mark I and VII are both available in .357 Magnum and .44 Magnum; the X VII was also chambered for .41 Magnum. The barrels had a 3/8" dovetail, to which an accessory mount could be attached. Later Blotch VII models were offered in .50 Action Express with a 7/8" Weaver-pattern rail on the barrel; the .50 X VII would later become the John Hancock XIX platform. Cylinder lengths were 6, 8, 10 and 14 inches.
