Abstract: The invention relates to a magazine for a handgun, comprising a chamber that accommodates the ammunition and a magazine head that is suitable for being accommodated by the magazine shaft in the breechblock housing of the gun, characterized in that according to the invention an ejector plate is arranged on the magazine head and means are provided for changing the relative position of said ejector plate in the magazine shaft when a magazine is inserted. The solution according to the invention makes it possible to change the position of the magazine head in the magazine shaft by means of an adjusting mechanism and thus to also change the relative position of the ejector plate, which is now on the magazine head, in the magazine shaft. In the process, the position of the ejector plate relative to the feeding web of the breechblock generally changes.

Abstract: This invention relates to a handgun comprising a weapon frame with a grip and a break-barrel unit (11) that can be tilted forward and that is comprised of at least two barrels. A firearm as per the invention provides for a bifunctional or multifunctional hammer unit, comprising at least two hammers (19) that can be moved independently of one another when the firearm is triggered; each hammer impacts only one firing pin (28) in each case of a firing-pin unit (27) comprising at least two firing pins (28, 29) in separated positions, wherein each firing pin is assigned to one barrel of the firearm in each case. A double-barrel or multi-barrel firearm is provided in a compact design in which the hammer unit is cocked with a relatively high amount of spring force with a relatively small amount of existing space. In addition, this invention provides a firearm that has less trigger weight.

Abstract: A changeover system is provided for a hand gun comprising at least two different barrels, able to be applied exchangeably on a first grip piece of a weapon, for bullets of different caliber, with at least two different magazines for cartridges of different caliber able to be applied exchangeably on a first grip piece of a weapon. Such a system has at least a second grip piece of the same weapon type, provided for a smaller caliber, on which at least one security arrangement against interchange is provided, which prevents the application of a barrel and/or of a magazine of a larger caliber on the grip piece provided for a smaller caliber. The user of a second large-caliber weapon can then mount components of the small-caliber weapon onto the grip piece of the large-caliber weapon, in order to fire small-caliber ammunition therewith, for example for training purposes.

Abstract: A versatile handgun comprised of a weapon frame with a grip and at least one gun barrel and comprised of at least one additional defense element differing from the actual firearm function that is arranged on the grip of the weapon or that is housed in the grip of the weapon. The handgun is capable of making help available in an emergency situation and is capable in so doing of covering a very broad range of dangerous situations. The additional defense element(s) and various other pieces of emergency equipment, medical devices and/or tools could be housed in a slide-in element and different types of barrels could be used.

Abstract: The present invention relates to a safety device for a firearm with a trigger bar in said firearm. The trigger bar moves in response to a pulling of a trigger. An actuator in said firearm is adapted to actively move said trigger bar between a first position and a second position. The trigger bar engages in the trigger induced movement with a hammer link for releasing a hammer and firing a cartridge bullet when the trigger bar is in the first position or first state. However, said trigger bar does not engage in the trigger induced movement with the hammer link, such that the cartridge bullet is not fired, when the trigger bar is in the second position or state.

Abstract: The present invention relates to a changeover system for a hand gun comprising at least two different barrels, able to be applied exchangeably on a first grip piece of a weapon, for bullets of different caliber, and/or at least two different magazines for cartridges of different caliber able to be applied exchangeably on a first grip piece of a weapon. According to the invention, the changeover system comprises at least a second grip piece of the same weapon type, provided for a smaller caliber, on which at least one security arrangement against interchange is provided, which prevents the application of a barrel and/or of a magazine of a larger caliber on the grip piece provided for a smaller caliber. If required, the user of a second large-caliber weapon can then mount components of the small-caliber weapon onto the grip piece of the large-caliber weapon, in order to fire small-caliber ammunition therewith, for example for training purposes.

Abstract: The present invention relates to a hand gun having at least one exchangeable magazine for cartridges, able to be inserted from below into a grip piece of the weapon. According to the invention, a security element is arranged in the grip piece of the weapon, which with the magazine removed blocks a grip security arrangement of the weapon on the grip piece and which on insertion of the magazine is acted upon by an element arranged on the magazine such that it moves within the grip piece, wherein through this displacement the blocking of the grip security arrangement is released.

Abstract: A barrel jacket covering at least partially the outer surface of the bullet-guiding barrel of a firearm is provided, wherein the barrel jacket has at least one inner casing and one outer casing and a spacer. The inner casing is arranged adjacent to the barrel, covering the barrel in a close-up position. The outer casing is arranged at a distance to the inner casing, covering the inner casing, thus providing a continuous gap. The continuous gap is stabilized by at least one spacer, which stabilizes the inner casing and outer casing in their relative positions.

Abstract: The present invention relates to a hand gun with a tensioning lever (cocking lever), connected with the lock, with a handle for cocking the weapon, for which at least two alternative fastening positions are provided for the handle for actuating the tensioning lever. The relative position of the handle for actuating the tensioning lever is changeable on the weapon, so that one can engage for cocking in various positions on either the right hand or left hand side, so that the tensioning lever can be adjusted to fit and be operated by a right-handed or a left-handed person.

Abstract: The present invention relates to a magazine for a hand firearm, which is detachably mountable to the weapon, incorporating a drum-like, approximately cylindrical housing (10) which accommodates a greater number of cartridges in an orientation parallel to the axis of the housing, further incorporating an approximately spiral-shaped divider device (9), which is located inside the housing and accommodates the cartridges, a driver plate (14), which is adapted for indexed rotation about its axis and is driven by the force of a spring, said driver plate causing the cartridges to advance to the next position on a spiral path after each shot, and a follower (18) disposed in said magazine, which causes the cartridges to advance on their spiral path, to exit said divider device and to enter into a magazine head (21).

Abstract: The present invention relates to a magazine (10) for a handheld firearm, suitable for accommodating a plurality of cartridges (11, 12, 13, 14) which are transported in a guided movement by means of a feed within the magazine in the direction of the barrel of a weapon, in order to be loaded individually in each case into the barrel of the weapon at the upper end of the magazine after each shot, with the cartridges being guided along a curved path in the magazine.
