Magnum Research Mark XIX Desert Eagle .429 DE/.50 AE 6″ Barrel 7-Rounds w/ Conversion Features:

Magnum Research has just made one the most popular calibers more potent with the introduction of their new .429 Desert Eagle cartridge, or .429 DE for short. When compared to a standard .44 Magnum (.240 grain, 6″ barrel), the new .429 DE exhibits a 25% increase in velocity and 45% increase in energy. Since it is essentially a .50 AE round necked down to a .44 caliber projectile, it is compatible with standard Desert Eagle .50 AE magazines and components, making adoption simple!
