The DESERT EAGLE PISTOL by I.M.I. is a semiautomatic magazine-fed, double-action pistol. The
safety of the DESERT EAGLE PISTOL locks the firing
pin, decock the hammer and also disconnects the
trigger from the mechanism.
In addition to the high accuracy of the polygonal
rifled barrels and low recoil, the DESERT EAGLE
PISTOL offers the convenience of firing standard
9mm Parabellum (9 x 19), .40 S&W and .45 ACP
in pistols with these caliber designations.
The anatomically formed grip dimensions permit
rapid, accurate, instinctive shooting. The combat
style trigger guard is designed for two-handed
shooting.
SLIDE-MOUNTED SAFETY
An easily operated slide-mounted thumb safety
and deep-groove serrated slide grip are designed
for positive operation.
FRAME-MOUNTED SAFETY
The models FS and F employ a frame-mounted
safety. This safety disconnects the trigger bar
from the sear while in the safe position. There
is a firing pin block.

OPERATING PRINCIPLES
RETRACTION MOVEMENT
Prior to firing the pistol, the barrel is locked in
position by three lugs engaged in three slots in the
slide assembly. Upon firing the pistol, propellant
gas pressure pushes the slide rearward. During this
movement, both barrel and slide recoil together a
short distance, then the barrel stops and disengages
from the slide; the slide continues its rearward
travel. When the bullet has left the barrel, the empty
cartridge case is extracted and ejected with the
continuing movement of the slide to the rear. At the
same time, the slide pushes the hammer down into
the cocked position, where it is retained by the sear.
The recoil springs are now compressed.
FORWARD MOVEMENT
When the recoil springs expand, they drive the slide
forward. During this movement the slide strips a
cartride from the magazine and inserts it into the
chamber. The locking lugs on the barrel once again
engage the slots in the slide and lock the cartridge
in the chamber.
CONTINUED FIRING
When the trigger is pulled, the sear releases the
hammer which in turn hits the firing pin thus firing
the chambered cartridge. Firing may be continued
in this manner until the magazine is empty. When
the last cartridge is fired and the empty case is
ejected the slide is retained in its rear position by
the slide catch. The slide is actuated by the
magazine follower. The slide catch will release the
slide when depressed by hand.
SAFETY FEATURES
The safety is located at the back of the slide, just
below the rear sight. Pushing the safety downward
will engage the safety. In this position the sear is
held down by the firing pin safety and the trigger
bar, which is pushed downward and cannot engage
the interrupter thus neutralizing the trigger. The safety
is also a decocking device which pulls the firing pin
inside the firing pin channel before the hammeris
released, preventing any contact between them. Due
to the unique blocking of the firing pin by the safety,
the pistol will not fire when dropped accidentally on
its hammer or muzzle.
