Real steel background: The IMI Desert Eagle is a very big pistol. The barrel is 6 inches long, it now comes in three calibers: .356, .44 mag, and .50 AE. The newest desert eagle can change in between the calibers with as little as a barrel change. KWC did a very good job on this gun. It actually has the real steel trademarks on it. KWC even cut the inner barrel off about half an inch short and widened the outer barrel to look like a .50 cal The Desert Eagle is reasonably heavy, it out weighs a tac master with the suppresor on it. It feels solid in your hand and the only parts that should be metal on the gun are the barrel, frame ,and slide. This is a gas gun, which means it's powered by gas and doesn't need to be cocked every time. It's fast, clean, inexpensive and easily maintained; it does not require batteries to operate. Also, spring guns are the toughest, most durable of all AirSoft guns, because they're made with few breakable pieces. If you're looking for a fun, reliable firearm that'll look great and perform even better, you've come to the right place.
