Concerning the reason for the Desert Eagle
Some folks may not remember this, but the Desert Eagle, in it's original .357, .41, and .44 Magnum chamberings, was designed and produced for a certain sport that was popular at the time.
Anybody? Anybody? Buehler? Here's a hint: IHMSA. Yup, Handgun Metallic Silhouette, reliably knocking over the steel chickens, piggies, turkeys, and rams, while transitioning to the next target - without cocking and overpressuring the pre-Cassull revolver, working the bolt on the XP-100, or reloading the Contender/Wichita/MOA Maximum. Tada, here's a gas-operated heavy autoloading pistol, capable of OhMyGawd velocities without tearing itself apart.
Now the fellow who wants to pack a brace of Desert Eagles in shoulder holsters for personal defense, he may have his priorities a wee bit off kilter...
Not that I refused to watch "Barb Wire" due to misapplication of Desert Eagles.
