There's no such thing as a 9mm Desert Eagle.
Desert Eagle specifically, no. The Jericho - also commonly called the "Baby Eagle" - is something of a scaled-down version of the Desert Eagle, and that is available in 9mm.
The Desert Eagle was never made in 9mm. If you're referring to the Jericho, aka, the "Baby Eagle", 500 - 900, depending on condition, accessories, and whether it's the straightforward 9mm or the convertible Jericho 941, which can also fire the .41 Action Express.

No. The Luger was a 9mm gun and the 50 Desert Eage is a 50 caliber gun. The 9mm round would fall out of the barrel, and if you did manager to get it to fire, you could damage the gun and/or hurt yourself.
