.50 Action Express

Developed in 1988 by Evan Whildin of Action Arms, the .50 Action Express was part of a program to upgrade semi-auto pistol performance through cartridge design. With 1,414 foot-pounds of muzzle energy, the .50 AE is one of the most powerful pistol cartridges in the world – a fact Desert Eagle fans well know. New shooters beware, this baby tends to produce a little muzzle flip.
