The Desert Eagle, in my opinion, is purely a collector's item and hardly practicial in real life situations. Concealing a weapon that is damn near a foot long would be insanely hard to hide in your jacket, purse, etc.

As for .50 calibre rounds tearing through engine blocks; that is only with rifles, I believe.

For real life purposes, I recommend getting a CZ series weapon, preferably either the CZ-75 or CZ-85 if you got the money for it. The CZ-85 is more expensive because it is newer, but the CZ-75 can still get the job done in a life threatening situation. I think both of the handguns use a .40 calibre bullet, meaning the weapon will not have much recoil, meaning more control over the weapon, not to mention packing much punch. I think both handguns cost around eight hundred, which is cheap compared to some that I have seen around, like H&K and Beretta handguns.

I do not recommend getting a small calibre handgun, like 9mm, .22s, .25s, .32s, or even .38s because they do not pack enough punch to stop a person in their tracks. I have heard of cases where thieves have been shot four times with a 9mm in the chest and stomach and was able to move around. Get something with Magnum rounds in it, or something over .40 calibre.
