Abstract: The inventive firing device (1) comprises a cartridge reception unit (11) in which each of several cartridges (3a to 3d) is provided with one propellant (132) and is interchangeably disposed in one reception chamber (9), and a cover part (7) closing the rear section of the device by means of which cartridges can be replaced. A fluid and/or powdered substance (14) that can be propelled by means of the triggered propellant (132) is stored in each cartridge. Triggering units for the cartridges (3a-3d) which can be activated sequentially by a trigger element (21) are disposed in the cover part (7). In order not to harm the user when replacing cartridges, the cartridge reception unit (11) and the top part of each cartridge are aligned with each other so as to seal the cartridge area (9) at least following the firing of the cartridge, thereby leaving no substantial quantity of the substance (14) in the firing device (1) outside the cartridges (3a-3d).

Abstract: The sear includes a first tang adapted to cooperate with the searing surface of the hammer. A second tang of the sear projects towards the firing pin. The firing pin has a sleeve like portion of an increased diameter defining an abutment surface. In the cocked position of the hammer the first tang of the sear contacts the searing surface of the hammer, and the end of the second tang is located in front of the abutment surface of the firing pin. Thus, when the gun is accidentally dropped, the firing pin cannot move for instance due to forces of intertia units own into the firing position striking unintentionally a loaded round.

Abstract: A rotatable shaft member supports a first control member and a second control member. The first control member cooperates with a tang of a rotatable sear. The second control member cooperates with an abutment stop of the sear. When the shaft is rotated to where the second control member contacts the abutment stop of the sear, the sear is blocked and the gun cannot be fired. When the shaft member is rotated such that the second control member is moved away from the tang of the sear, the gun can be fired. When the shaft member is rotated further such that the second control member is remote from the abutment stop and the first control member contacts the tang of the sear, the tang moves out of contact with the searing surface of the hammer. The hammer begins to pivot in a gun firing direction until the tang engages a half-cocked notch for stopping movement of the hammer, whereby the hammer is decocked.

Abstract: The sear is rotatably supported in the frame of the firearm to rotate around an axis of rotation. The hammer is pivotally mounted in the frame to pivot around a pivot axis. The hammer includes a striking surface. The sear includes a blocking surface which cooperates with a resting surface of the hammer. The position of the blocking surface of the sear which is determined by its axis of rotation, the position of the striking surface of the hammer, which is determined by the location of the pivot axis of the hammer, and the position of the rear end of the firing pin are selected in such a manner that when the hammer is in its decocked position, in which position the resting surface contacts the blocking surface, the striking surface of the hammer is at a distance from the rear end of the firing pin. Accordingly, the hammer does not contact in its decocked state the firing pin such that eg upon a dropping of the firearm a shot may inadvertently be fired.

Abstract: The gun can be switched to operate either in a double action or as single mode. A pin located in the slide can be rotated from a position, in which a jacket surface is flush with the bottom surface of the slide to a position where a nose projects above the bottom surface of the slide. The sear has a control cam which is acted upon by the nose of the pin when in its projecting state. The hammer includes a detent member having two abutment shoulder sections adapted to cooperate with a control edge of the sear. If the pin is in a position, in which mentioned jacket surface is flush with the bottom surface of the slide, it does not act upon the control cam of the sear such that upon the loading or a firing of the gun, the hammer is held in the fully cocked position, in that the first control edge of the sear engages the forward abutment shoulder section of the detent member. This is the single action mode.

Abstract: A rotatably mounted hammer lock member has a hammer stop abutment. The trigger rod has a first operating projection received in a recess of the hammer lock member such that a reciprocal movement of the trigger rod causes a corresponding rotational movement of the hammer lock member. An interrupter member is hingedly mounted to the hammer. A projection at the rear end of the trigger rod is loosely received in a recess of this interrupter member. The rear end of the trigger rod includes a chamfered control surface area. The frame of the gun includes a corresponding chamfered control surface area. When the trigger rod is moved by the trigger for firing the gun, it rotates the hammer lock member such that its hammer stop abutment will be moved out of the way of the hammer.

Abstract: An arrresting pin having a recessed circumferential section is inserted in the frame of the gun. A pin locking spring is biased into the mentioned recess. This locking spring prevents the arresting pin from falling out of the frame. A simple rotation of the arresting pin moves the locking spring out of the way, allowing an easy disassembling. The arresting pin includes further a planar jacket section, co-operating with a corresponding abutment surface at the slide for limiting the travel during the recoil of the slide.

Abstract: The magazine, which is usable specifically for hand guns, is capable of storing cartridges of various sizes, i.e. diameters. The magazine lips are bent inwards with such a curvature that their inner surface defines part of a jacket of a cylinder, which has a diameter which corresponds substantially to the diameter of the base of the largest cartridge which the magazine can store. The uppermost edges of these magazine lips extend at an angle relative to each other such that they diverge in the firing direction of the magazine. The distance between these edges is at any point along their extent smaller than the diameter of the smallest cartridge which can be stored in the magazine. A spring biassed feeder within the magazine has a cartridge support surface, which includes a bulged surface section. This bulged surface section ensures a line contact with any size cartridge or shell, respectively, which is stored in the magazine.

Abstract: A locking plunger which is perpendicularly movable relative to the direction of movement of the firing pin allows or prevents the axial movement of the firing pin to fire the gun. This locking plunger is spring biassed to abut a safety lever which is part of the sear of the operating members of the gun. The safety lever is located and arranged such on the sear that it allows a movement of the locking plunger into the firing pin unlocking position upon the operating members of the gun reaching the end of the trigger slack. Accordingly a movement of the locking plunger into the unlocking position will proceed not earlier than the sear snapping into the firing position. Any other accidental limited movements of the operating parts of the gun including such of the hammer cannot cause an axial movement of the firing pin because such movement is positively prevented by the locking plunger. Therefore, an accidental firing of the gun is positively prevented.
