How out Fig. 1 it can be seen, a handgun according to the invention essentially comprises a handle 1, a closure housing 2, a closure piece 3, a barrel 4, a firing pin 5, a removal unit 6 and a mold handle 7. Furthermore, are made Fig. 1 a rear sight 8 and a magazine 9 can be seen.

The closure housing 2 is firmly connected to the handle 1 in the use state of the handgun. This happens on the one hand via one Fig. 1 apparent dovetail guide 10 on the handle 1, in which a corresponding guide of the closure housing 2 can engage. Furthermore, the closure housing 2 and handle 1 are connected to each other in the rear direction in the weft direction by interlocking parts. The determination of the closure housing 2 on the handle 1 via a locking shaft 11th

The barrel 4 is in the closure housing 2 by means of a likewise from Fig. 1 apparent retaining clip 12 set, both from Fig. 1 as well as out Fig. 16 is apparent. For the determination of the barrel 4 has a on both sides a piece far over the circumference extending groove 13. In particular shows Fig. 16 a section through the closure housing 2 and the barrel 4 in the region of this groove 13. In the region of the groove 13, the closure housing 2 has a slot 20 for the introduction of the retaining clip 12. The retaining clip 12 has, as in particular Fig. 16 it can be seen, a substantially U-shaped form with two in the position of use of the handgun downwardly extending legs 14, 15. These legs 14, 15 partially surround the barrel 4 in the region of the groove 13, so that in this way a positive connection between the barrel 4 and the closure housing 2 is achieved.

The closure piece 3 is relative to the barrel 4, the closure housing 2 and the handle 10 in the longitudinal direction of the firearm displaceable. In particular, the closure piece 3 moves backwards when a shot is fired. The closure piece is detachably connected to a closure spring bar 16 which can guide a non-illustrated closure spring. Upon triggering a shot, the closure piece 3 and with it the shutter spring rod 16 is moved back against the force of the closing spring. The closing spring is supported on a non-illustrated point on the closure housing 2 and is compressed by the movement of the closure piece 3 to the rear. As a result of the relaxation of the closing spring, the closure piece 3 and with it the closure spring bar 16 are subsequently moved back again into the starting position. During this forward movement, another cartridge is loaded into the barrel 4 from the magazine 9.

At the front end of the shutter spring rod 16, a piston 17 is provided (see Fig. 2 ), which compresses a substantially cylindrical volume in the interior of the closure housing 2 during the forward movement of the closure spring rod. By this compression, a damping device is provided, wherein the part of the closure housing 2, which has the volume to be compressed, is provided with a throttle opening for the exchange of air. By dimensioning the throttle opening, the strength of the damping device can be specified. Therefore, the throttle opening is variable in size.

There is alternatively or additionally the possibility that the or a damping device causes a damping of the movement even in the backward movement of the closure spring rod 16 and the closure piece 3. For example, in the backward movement of the shutter spring rod 16 through the throttle opening air can be sucked into the cylindrical volume. With appropriate dimensioning of the opening, this can be done so slowly that a negative pressure in the cylindrical volume arises, which counteracts the movement and thus slows down or damps it.

The closure piece 3 also has handles 18, which are attached to the closure piece 3 in such a way that they are accessible to the user outside the closure housing 2. The handles 18 are connected via flat fastening means with the closure piece 3, which protrude through corresponding recesses 19 in the closure housing 2. On the handle 18, a user can engage to pull the closure piece 3 against the force of the closure and firing pin spring backwards.

The handle 1 has at its rear end a receptacle 21 which has a partially hollow-spherical structure (see Fig. 5 ). The handgun further comprises a retaining plate 22 with a spherical bearing surface 23 (see Fig. 1 and Fig. 5 ). The retaining plate can be connected to the mold handle 7, so that in the assembled state of the handgun (see Fig. 5 ) the spherical contact surface 23 can be fixed by means of the screw 24 in the hollow spherical receptacle 21. After loosening the screw 24 of the mold handle 7 can be largely arbitrarily pivoted, so that the aforementioned hollow spherical Receiving 21 and the spherical bearing surface 23 form a 3-D adjustment for the adjustment of the mold handle 7 on the handle 1.

In the handle 1 and in the closure housing 2 is further provided in each case a recess 25, 26 for the magazine 9. Through the recesses 25, 26, the magazine 9 can be inserted from above. Inside the handle 1, the magazine 9 hits after insertion from above on a movable element, against the force of a tension spring 27 (see Fig. 13 ) can be pushed down. The magazine 9 has on each of its longitudinal sides a slot 28 and a recess 50 (see Fig. 19 ). In the latching recess 50 may include an encompassed by the handle 1 locking element 29, which is connected via a transverse shaft with a control knob 30 (see Fig. 18 ).

By pressing the control knob 30, the locking element 29 is pressed out of the recess 50, so that the magazine 9 is pushed by the force of the tension spring 27 upwards. Furthermore engages by pressing the control knob 30 connected thereto engaging part in the slot 28, so that the movement of the magazine 9 upwards only until the stop of the engaging member at the lower end of the slot 28. After pressing the control knob 30 so the magazine 9 moves only slightly up and remains in this position. By releasing the control knob 30, the engaging member is pushed out of the slot 28, so that then the magazine can be completely pulled out of the handle 1 and the closure housing 2 upwards.

In the Fig. 18 illustrated embodiment is suitable for right-handed people who can operate the control knob 30 with left. For Lefthanded a mirrored control knob 30 can be used with shaft and locking element 29.

The removal unit 6 has, as in particular 10 to FIG. 12 it can be seen, a trigger 31 which is pivotally connected to a trigger bar 32. By pressing the trigger 31, the trigger bar 32 is left in 10 to FIG. 12 , or pulled back against the firing direction of the handgun. By the movement of the trigger bar 32 to the rear of a trigger lug 33 which is pivotally mounted on the Abzugeinheit, released so that it can swing away down. The sear 33 has on its upper side a step 34, at which a later to be described in more detail locking edge 35 of the firing pin 5 can rest from behind. By pivoting down the trigger lug 33, the step 34 releases the latching edge 35 so that the firing pin 5 can move forward.

The firing pin 5 includes, as this particular Fig. 1 it can be seen, one of the locking edge 35 to the front extending firing pin spring rod 36 on which a firing pin spring is supported. At the rear end of the firing pin 5, a triggering edge 37 is mounted, which can impinge on the edge of a cartridge located in the rear end of the barrel during the movement of the firing pin forward and can ignite it.

The weapon has a match pressure penalty. These types of prints are known in sports weapons. The triggering of the firing pin 5 takes place in two stages. First, the trigger 31 is moved against a relatively small force of a spring 45 included by a spring means 45 until the edges of a trigger pawl 43 and the Abzugstollenens 33 are just before the separation (preferred way). Now only a minimally small way is necessary to separate pawl 43 and sear 33 from each other, so that the sear 33 pivoted about its pivot point, the striker 5 releases and thus triggers the shot. In order for the shooter to see when the pawl overlap 49 approaches zero and the firing pin is released, it is provided in the case of such types of fume hoods to suddenly increase the pull-off force (pressure point). This is practically realized by the application of a second spring force on the trigger, for example by a first spring pressure pin 46 (see FIGS. 20, 21 and 22 ). Thus, the total pull-off force results from the sum of the preferred force and the pressure point force. For the disciplines to be shot with this weapon, there are also rules for the minimum withdrawal force, which is either 1360g or 1000g. Due to manufacturing tolerances and individual Einstellwünschen the parameters Vorzugkraft, Vorzugweg, pressure point force and position of the pressure point must be adjustable. The position of the pressure point is changed by turning the complete first spring pressure pin 46, the pressure point force by more or less strong bias of the inner spring by means of a threaded pin. In conventional prints, it is relatively expensive to change the pull-off force from 1000g to 1360g, since the change in setting must be checked by means of measuring instruments - these meters are often not available.

In the present invention, a second, switchable spring force is provided on the trigger. For this purpose, the removal unit comprises a second spring-pressure pin 47 which has a thread and a stop 48 at its outer diameter. After prior force adjustment can by removing / unscrewing this spring pressure pin 47, the pull-off force be reduced by one level. If this is to be increased again, only the spring pressure pin 47 has to be screwed back into the trigger housing until it stops.

From Fig. 1 and in particular FIGS. 14 and 17 apparent rear sight 8 can be attached by means of a dovetail-shaped recess 38 to a corresponding Anformung 39 at the rear end of the closure housing 2. In the region of the recess 38, a locking screw 40 is arranged on the rear sight 8 in order to allow a secure fixing of the rear sight 8 to the closure housing 2. Depending on the handedness of the shooter, the shaping grip 7, which can be adjusted in position, has a palm rest 41 on its left or right lower side, which has a length l of approximately 110 mm. The handgun has a maximum length of 300 mm with a maximum height of 150 mm and a maximum width of 50 mm. Furthermore, the barrel is about 153 mm long.

The corn 42 arranged on the upper side of the closure housing 2 corresponds to the rear sight 8.
