The Desert Eagle is a powerful semi-automatic pistol available to both teams. It is chambered with .50 Action Express which makes it able to deal high amounts of damage. It is the most powerful handgun in the Counter-Strike series. For this reason, the Desert Eagle is one of the most popular and widely used weapons in the Counter-Strike games. Currently in Counter-Strike: Global Offensive it costs $800 as opposed to $650. The movement speed of this weapon is 250 units per second, meaning they don't suffer any speed reduction. However, in Global Offensive it has a movement speed of 230 units per second, which is suffering a moderate speed reduction. When comparing to other secondary weapons, it has the slowest movement speed of all pistols.
While wielded, the player's movement speed is 250 units per second, meaning they suffer no speed reduction. However, in CS:GO the player's movement speed is reduced to 230 units per second. The Desert Eagle is one of the many weapons able to shoot underwater.
The Desert Eagle in the Counter-Strike games comes in two finishes: Black (used only in Deleted Scenes) and chrome silver (used in all other games), the sound is slightly different, too. In Global Offensive, the Desert Eagle instead has a dust-color shiny finish.
The Desert Eagle in Counter-Strike is based on the IMI/Magnum Research Desert Eagle Mark XIX chambered in .50AE. However, the version depicted has slits in the barrel (known as a "fluted barrel") that were only used in .44 Magnum and .357 Magnum models of the Mark XIX. The black Desert Eagle from Deleted Scenes lacks the fluted barrel in addition to the slits in the top of a standard Mark XIX barrel. The model in Global Offensive lacks this and has other markings confirming it as a .50
It is odd that the Desert Eagle is in Counter-Strike, because no police or military forces have (or ever for that matter) used it in any of it's variants/calibers due of loud noise and heavy penetrate power.
The "Eagle head" marking on the operating slide only appears in early Counter-Strike games until 1.6 version.
Before the August 10th, 2012 update, the Desert Eagle in Global Offensive shared its draw and reloading animations with the Glock-18, P2000, P250, and Five-SeveN.
Reloading animations that are currently in use for Desert Eagle in Counter-Strike: Global Offensive are remade pistol animations from the Alpha stages of the game.
