The Desert Eagle typically holds 9 rounds in its magazine for the .44 Magnum caliber version and 7 rounds for the .50 AE version. Some models may have variations in magazine capacity, but these are the standard capacities for the most common calibers. It's important to check the specific model for exact details.

None.
You have to be more specific. Looking at the "Magazine" or "clip" can give you a good idea on how much ammo a weapon can hold. Also the caliber size of the ammo is a factor to how much ammo is in a "Magazine/clip".
100-1000 usd depending on specifics
Pretty much a 1:1 copy
usually in a A-10 II carries 1,200 ammo, which at maximum R.P.M. can be expended in 17seconds
"Magnum" refers to the cartridge, not the firearm. The Desert Eagle fires Magnum cartridges. What you're probably asking is the difference between a revolver chambered for Magnum cartridges, and a Desert Eagle semi automatic pistol. Of the two, the revolver would typically be much more practical.
Probably around 60 to 70 dollars
2000-2500 USD or so
i saw a gold plated one going for 3k at a store
An eagle can typically carry prey that is up to half of its own body weight while flying.
The Desert Eagle has significant recoil but it is not punishing because the automatic action will take up some of the force to chamber the next round. You'll still want to hold onto it with both hands and KEEP YOUR HAND OUT OF THE WAY OF THE SLIDE.The hottest load you want to feed it (.50 cal) will produce 1,646 ft·lbf of force.The effect will be much worse for you if you are on the receiving end of this pistol.
