The Mark XIX configuration supports caliber interchangeability across compatible barrels, bolts, and magazines, offering flexibility within the Desert Eagle platform. This example is the DE50 variant chambered in .50 AE with a 7+1 capacity.
The 6 inch carbon steel barrel uses polygonal rifling with a 1:19 RH twist to support the .50 AE cartridge. Fixed combat sights (front blade, rear notch) and an approximately 8.5 inch sight radius provide a clear, straightforward sight picture.
The pistol operates via a gas system with a rotating bolt and is single-action only. Controls include an ambidextrous manual safety and an external spurred hammer. Rear cocking serrations aid slide manipulation.
Construction is all carbon steel with a uniform black oxide finish on the frame, slide, and receiver. Black two-piece textured polymer grip panels with molded Magnum Research bird logos offer full-hand coverage.
Mounting features include an integral top optics rail machined into the barrel; there is no underside accessory rail on the frame/dust cover. Factory markings include: 50AE, DESERT EAGLE PISTOL R MADE IN USA, and MAGNUM RESEARCH INC., PILLAGER, MN USA.
