THE ASTRA
CALIBER .22 SHORT
The Astra «Cub», Model 2000, utilizing caliber .22 Short ammunition,
was built with regard to the same principles, both mechanical and
ballistic, on which the function of all models of Astra pistols is based.
In its design this pistol was destined for use in pi inking or personal
defense. Inherent in this pistol are the best conditions for this utili-
zation and, what is more, it is sturdy, perfectly adjusted and mecha-
nically precise. This is characteristic of all the arms produced by Astra-
y
Unceta
exclusively to the manufacture of firearms which are universally
accepted. This guarantees the perfection of the «Cub» pistol, since
it assures that past experiences were fully referred to before th2
pistol was placed on sale.
The Astra «Cub» is a firearm of semi-automatic type with magazine.
It has an exterior hammer, by which the pistol can be easily cocked
with a simple motion of.the thumb. The total weight of the pistol
is carefully distributed to assure perfect balance, and the shape of
the grip and the position of the trigger both contribute to natural
«pointing» and ease in firing.
1.-The pistol is provided with a thumb safety (Figure 1) so located
that it is easily reached by the thumb when the pistol is held in the
right hand, making it simple to change the safety lever from «safe» to
«fire». This safety acts on the trigger which remains locked to all
movement when the body of the safety is opposed to the mass of
the trigger, thus preventing movement of the trigger. When the thumb
safety is turned to fire position (Figure 2) the safety bar no longer
blocks the trigger, allowing movement of the trigger for firing
(Figure 3).
2.- The pistol also has a magazine safety, which guarantees additional
safety of the arm when a live round is in the chamber, thus permitting
firing of the cartridge only when the magazine is replaced. In effect,
(Figure 4), the magazine, when in place, maintains the piece «a» in
such a position that no part of it obstructs the trigger. However,
when the magazine is removed (Figure S), the piece «a», through
the action of its self-contained spring, engages a notch in the trigger.
thus preventing any movement of the trigger and oischarge of the
gun. Because of the contact between the sear and the hammer, the
pistol. when loaded and with the hammer cocked, cannot be dis-
charged involuntarily. The pistol in this way is secure and safe and
even if the hammer accidentally releases while cocking there is little
risk that the pistol will fire. To fire the pistol it is necessary that the
trigger actually be pulled, requiring voluntary action to do so. In
effect, when the hammer is cocked (Figure 6), it is drawn back on
its axis from position I to position II, at the same time, the sear, mov-

ing also on its axis, is displaced and comes to rest in the notches
or teeth of the hammer. Once in position II the hammer remains
immovable, so placed that the point of the sear is engaged below the
second tooth or notch of the hammer, thus impeding its advance.
Only when the shooter, pressing on the trigger, causes the trigger
bar to bear against the sear, moving it to position III, the hammer is
then launched forward against the firing pin. If, when the hammer
is in the motion between position I and position II, it should slip
from under the thumb of the shooter, it would come to rest on the
first tooth against the sear (half cock notch), position IV, thereby
rendering it safe.
