Comments: This is a big gun and a real handful to shoot. It has true blowback action with a loud report and a noticeable recoil. Despite the recoil, the gun is fairly easy to hold on target and is capable of tight groups. It uses the same 8-shot magazine as other Umarex pistols. Because some gas is used to operate the slide, only about 30 good shots are available from each CO2 cartridge. The blowback action cocks the hammer after each shot, but the first stage of the two stage trigger is used to rotate the magazine. This makes the first stage a little uneven, but the second stage has a light break with only a small amount of creep. The blow-back portion of the slide has no lock-open mechanism and does not lock in the open position after the last shot is fired. The lever that looks like the firearm's slide lock lever is used to open the loading port on the airgun. This all plastic gun is a visually faithful replica of the Desert Eagle with good fit and finish and is a lot of fun to shoot. It is the first blow-back operated pellet pistol to hit the market since the Crosman Model 451 from 1969.

Performance: Measurements were made on 8/31/06 at a temperature of 82 F and 14' elevation. A ten shot string was fired from a bench rest at 15' using JSB Match Diabolo pellets (8.0 gr). The highest velocity measured was 464 fps, the lowest was 426 fps (average of the 10-shot string was 444 fps). A six shot string fired with open sights grouped at 0.40".

Loading Pellets: Pushing down on the slide lock lever opens the loading well. The Desert Eagle uses the same 8-shot metal clip as other Umarex pistols. Pellets are loaded in the clip with the skirts on the same side as the ratchet tabs. The clip is placed in the well with the ratchet tabs pointing to the rear.

Loading CO2: While the CO2 loading and piercing system works well, it is slow and requires the user to have a special tool (or coin) handy to remove the threaded brass plug. I would have preferred for Umarex to have used the CO2 system employed on the CP99. This would have imparted an even greater sense of realism to the operation of the Desert Eagle.
