DESCRIPTION:
BRIEF SUMMARY
TECHNICAL FIELD OF THE INVENTION
The invention relates to a self-loading pistol in the form of a mechanically locked recoil loader, consisting of a barrel, a barrel casing, a stock housing a magazine, sliding in the barrel casing a breech member with striking pin and sighting device, a striking lever with trigger and trigger arm, a safety device, and a locking member movably mounted under the barrel.
BRIEF DESCRIPTION OF THE PRIOR ART
In self-loading pistols of this kind, the locking member movably mounted under the barrel serves to connect the barrel casing rigidly with the breech member for a limited joint rearward sliding movement, the locking member being controllable into the release position by control surfaces on the stock, while the breech member, sliding back alone, tensions at least one return spring, ejects the empty cartridge case, cocks the striking lever and, during the closing motion, re-loads from the magazine. A self-loading pistol constructed according to this principle is the firarm known under the name of Walther pistol.
In such a self-loading pistol, the striking lever can be moved by hand, by the trigger, and by the recoil movement of the breech member, into the cocked position under the tension of the striking spring acting via a striking rod and be held in this position by a spring-loaded trigger pawl. The trigger is coupled with the striking lever via a trigger arm, and the striking lever can be disengaged by cams as a function of the relative motion between the trigger arm, breech member and stock, respectively. Shooting is possible with the striking lever precocked or alternatively with the striking lever being automatically cocked by the cocking trigger with each shot. It follows that the striking path of the striking lever after a shot is fired differs in length; in particular, when shooting with the striking lever precocked, it is longer than when shooting with the trigger. In view of this different length of the paths, the striking spring must be made strong enough to accelerate the striking lever sufficiently also if the striking path is relatively short.
In such self-loading pistols the safety devices are extremely complicated and not always easy to operate. In the case of all these safety devices, the actuating member, accessible from the outside, is arranged movable on the side of the firearm, usually as a pivotable safety lever. Such a safety device is to be operated with one hand either for right-handers only or for left-handers only. It is another disadvantage of the known safety device that, when drawing the weapon, it cannot readily be seen at a glance whether the weapon is secured.
In such self-loading pistols, the sighting device is designed differently depending on whether utility hand firearms or sports weapons are involved.
The sighting edge is to be adjustable at least sideways. But also a height adjustment of the sighting edge is often desirable. The known sighting devices are extremely complicated and cause the sighting edge to stand out far beyond the breech member, thereby making it difficult to handle the weapon, and if the sighting edge is changed frequently, they easily lead to damage.
OBJECTS OF THE INVENTION
It is an object of the invention to provide a self-loading pistol of the kind more specifically defined above in which the disadvantages pointed out are avoided.
In particular it is an object of the invention to provide a self-loading pistol which is of an extremely sturdy and simple design and greatly improves the reliability and life of its parts also when used under rough conditions.
It is further an object of the invention to develop the self-loading pistol so that the cocking trigger moves very smoothly and that in a simple construction only a relatively weak striking spring is needed without the possibility of misfire occurring.
It is further an object of the invention to design the self-loading piston so that the safety device of the pistol can be operated easily and quickly by left-handers as well as by right-handers, and that, when
