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.

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: There is disclosed a barrel jacket covering at least partially the outer surface of the bullet-guiding barrel of a firearm, 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 arrange 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 stabilized the inner casing and outer casing in their relative positions.

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: 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 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 invention discloses a compressed gas-operated pistol (1) with a gas capsule (15) arranged in a grip member (5), which is in operative connection with a valve system (33) of the pistol (1). The secure receipt and piercing of the gas capsule (15) is effected through an abutment (17) which completes an inherent displacement and an external displacement superimposed on this inherent displacement. The external displacement is thereby effected by a support element (23) of the abutment (17) which is contacted by capsule tensioner (25). (FIG. 2).

Abstract: The invention discloses a compressed gas-operated firearm (1), especially a pistol, which at the utilization of a drum (18) for multi-shot projectile receipt distinguishes itself through a linearly displaceable weapon barrel (3) to achieve a loading position, or, respectively, firing position, and through a trigger (4) which is automatically secured against actuation in the loading position. Furthermore, a new type of valve system (25) is proposed for the impulse-like emission of the compressed gas upon the discharge of a shot.
