![]() ![]() The bottom lug of the bolt pushes a new round into the chamber, then the bolt locks up and the gun can be fired again. The slide reaches its rearmost position, then moves forward again under tension of the recoil springs. The spring loaded ejector is continually being depressed by the case, until the case is free of the chamber and the tension from the ejector is released, causing the case to eject, breaking free of the extractor in the process. ![]() A mechanism on the left side of the bolt prevents the bolt from rotating freely as the slide moves, forcing it to remain aligned correctly with the barrel while the breech is open. When the gases reach the cylinder, the piston pushes the slide rearward, with a large pin inside the camming surface in the rear of the bolt causing the bolt to rotate and unlock. The slide, which acts as the bolt carrier, has a small piston on the front that fits into this cylinder. These travel forward, through a small tube under the barrel, to a cylinder underneath the front of the barrel. When a round is fired, gases are ported out through a small hole in the barrel in front of the chamber. The Desert Eagle uses a gas-operated mechanism normally found in rifles, as opposed to the short recoil or blow-back designs most commonly seen in semi-automatic pistols.
