Ever since it was first introduced, the semi-auto magnum from Israeli Military Industries has been a favorite for film and books. It's appeared in the hands of darn near every action hero and heroine to grace the screen and comics.
The pistol has been in production since the 1980s, in over twenty variants and at least five different calibers. It is a magazine fed, semi-automatic handgun boasting a unique triangular-shaped slide and utilizes a gas-blowback system normally found in rifles.
For the Stone Soldiers, the Mark XIX variant is used, in .50 Action Express caliber- a round sufficiently strong enough to drop any human, and most inhuman targets (which is understandable given the round's design for use in medium to big game hunting). With a seven round magazine, plus one in the chamber, the XIX offers a much larger, and far more powerful round than the aged M1911 once used by the Detachment. Weighing in at over 4 pounds, the Desert Eagle is a heavy weapon best left for use by super soldiers.
