A receiving device receives the carriage at least partially in the rear end position. A shoulder support can be connected to the receiving device via a holding device.

Description

The invention pertains to a handgun, particularly a self-loading pistol.
The present invention particularly pertains to a pistol that comprises a frame, a carriage and a barrel and in which a receiving device at least partially receives the carriage in the rear end position. The pistol furthermore comprises a shoulder stock that can be connected to the receiving device by means of a holding device.
According to the present invention, the term carriage refers to the external component that is movable in a carriage guide, wherein the carriage can be moved forward relative to the frame in the carriage guide up to a front end position and moved backward relative to the frame in the carriage guide up to a rear end position.
Pistols are known from the prior art. These pistols are primarily used by the police, the armed forces, hunters and/or marksmen.
The pistols known from the prior art have the disadvantage that they have to be held in a stable position in an essentially unsupported manner during the time required for actuating the trigger, as well as for a short time thereafter. In this context, it is important that the pistol is already held in a stable position during the actuation of the trigger and the search for the pressure point because any jerking of the pistol immediately prior to firing the shot ensures that the bullet misses the target.
In a one-handed firing stance—with extended or angled arm—any motion of the upper body, which may also be caused by an unstable footing, is transferred to the pistol and can lead to tilting thereof immediately prior to firing the shot or while the shot is fired such that the bullet misses the target.
In a one-handed firing stance with a pistol known from the prior art, the pistol may also jerk and/or tilt when firing in dependence on the respective situation and the training and experience level of the user, potentially due to nervousness, and therefore miss the sighted target.
In emergency situations, in which a pistol cannot be purposefully fired due to lacking routine, nervousness and possibly subtle handling, persons can be inadvertently harmed and/or object can be damaged.
In addition, pistols with an external breech system, i.e. the movable component of the pistol in the form of a carriage, represent a significant risk of injuries for the user at least in special situations. In pistols with external breech systems, the carriage explosively moves backward in the direction of the user for the reloading process in order to eject the cartridge case of the fired cartridge and to feed a new cartridge from the magazine to the cartridge chamber during the subsequent forward motion. In this case, it can occur that the user respectively holds the pistol very close to the body or in the vicinity of the face in order to better capture the target with the sighting mechanism such that the carriage injures the face during its backward motion. This is particularly the case if the pistol is equipped with an optical light dot sighting mechanism because the light dot sighting mechanism is held very close to the eye and the pistol is therefore held very close to the face in order to acquire an optical sighting line between the eye and the sighting mechanism.
Injuries in the region of the face can also occur when using a notch and bead sighting mechanism if the pistol is not properly held and used, due to the recoil of the weapon and/or due to the backward motion of the carriage.
In a firing stance with angled arms, which are placed against the upper body for reasons of enhanced stabilization, the pistol is also positioned very close to the face in order to acquire an optimal sighting line between the eye, the sighting mechanism and the target. In this case, the user may also be injured due to the recoil and the backward motion of the carriage.
Known pistols also have the disadvantage that an optical light dot sighting mechanism can frequently only be mounted on the movable carriage, primarily for construction-related reasons. This quickly leads to material fatigue in the sighting mechanism and readjustments of the sighting mechanism because the sighting mechanism is subjected to high acceleration forces during the reloading motion of the carriage. Frequent and costly servicing of the pistol in this respect is therefore required.
The present invention is based on the objective of at least partially eliminating the disadvantages of the prior art. This objective is attained with a pistol according to claim 1. Preferred embodiments of the invention form the objects of the respective dependent claims.
Accordingly, the pistol comprises a frame, on the upper side of which a carriage guide extending in the longitudinal direction is arranged. This carriage guide is suitable for at least partially receiving and/or guiding a carriage and a barrel with a cartridge chamber. In this case, the barrel is at least partially received inside the carriage. The carriage can be moved in the carriage guide between a front end position and a rear end position. The carriage in the carriage guide closes the barrel in its front end position. The carriage in the carriage guide opens the barrel in at least the rear end position. The cartridge chamber in the barrel is visible when the carriage is held in the rear end position.
The frame furthermore comprises a carriage catch lever for locking the carriage. The carriage catch lever serves for locking the carriage in its rear end position. The cartridge chamber in the barrel is visible when the carriage is held in the rear end position and the carriage catch lever is moved from its lower position into its upper position. In order to disengage the locked carriage, the carriage catch lever is moved from its upper position into its lower position such that the carriage is moved from its rear end position into its front end position.
The pistol also comprises a trigger that is movable relative to the frame. When the trigger is actuated, a shot is fired and the self-loading process is carried out by moving the carriage backward and forward. The pistol furthermore comprises a grip with a magazine well for inserting a magazine containing cartridges.
The frame of an inventive pistol comprises a receiving device that at least partially receives the carriage in the rear end position. The receiving device is designed in such a way that it extends the frame by the length of the carriage motion into the rear end position and therefore advantageously encloses the carriage at least partially in its rear end position, particularly in an at least partially covering manner with a sighting mechanism. Due to the inventive design of the receiving device, the backward motion of the carriage in the direction of its rear end position takes place into the enclosing receiving device when a shot is fired. An injury due to the backward motion of the carriage is thereby prevented.
The pistol also comprises a shoulder stock that can be connected to the receiving device by means of a holding device. The receiving device is advantageously designed in such a way that it comprises a holding device for receiving a shoulder stock for the pistol. When a shoulder stock is received in the receiving device, the pistol can be pulled against the shoulder in a stabilizing manner and therefore fixed on the shoulder during its use. Fixing the pistol on the shoulder by means of the shoulder stock enhances the stability of the pistol and reduces jerking and/or tilting of the pistol when a shot is fired. Since the upper body provides a stable support for guiding and holding the pistol, e.g. in situations with unstable footing and/or tension or nervousness, the pistol is fixed and inadvertent motions of the arms or as a result of the footing are dampened and reduced. In this respect, the position and the accuracy of the pistol are advantageously enhanced by fixing the pistol on the shoulder. This advantageously prevents persons from being inadvertently harmed and/or objects from being inadvertently damaged.
In an embodiment of the invention, the receiving device is realized integrally with the frame, wherein the receiving device and the frame are particularly made of one material.
In another embodiment, the receiving device may be separably connected to the frame. In this embodiment, the receiving device is realized in the form of an adapter that can be pushed, attached, clipped and/or clamped on the frame. This has the advantage that older pistol models, particularly different models of various manufacturers, can also be retrofitted, e.g., with a corresponding retrofit kit in the form of the receiving device. In this way, the precision and accuracy of these models can also be enhanced by means of the inventive shoulder stock.
In an embodiment of the holding device, the shoulder stock can be positively and/or non-positively connected to the holding device by being inserted therein. Due to this plug-in design of the holding device and the shoulder stock, the user can decide whether the pistol should be used with or without inserted shoulder stock. The rear end position of the carriage is still covered such that the possibility of an injury is additionally reduced. The shoulder stock can be simply inserted into the holding device in situations, in which such a shoulder stock is required.
In an embodiment of the holding device, this holding device comprises a disengageable locking mechanism for fixing the shoulder stock. The shoulder stock can be advantageously inserted into the holding device and fixed therein by means of the locking mechanism. The shoulder stock is unlocked from the holding device by disengaging the locking mechanism such that the shoulder stock can be removed from the holding device.
In another embodiment of the holding device, the holding device comprises a hinge for connecting the shoulder stock in a pivotable manner. Due to this pivotable connection, the shoulder stock can be pivoted toward the right or the left outer lateral surface of the frame depending on the design of the hinge and then placed against one of the outer lateral surfaces of the frame. The shoulder stock is in a folded position when it is placed against one of the outer lateral surfaces of the frame. The folded shoulder stock may be simply placed against the left or the right outer lateral surface of the frame depending on the design of the hinge or locked thereon such that the shoulder stock is no longer able to move. In one embodiment of the hinge, this hinge may comprise a detent mechanism that prevents the shoulder stock from being unfolded by applying an excessively low force such that the shoulder stock no longer has to be locked on the lateral pistol frame.
In the embodiment of the holding device with a hinge, the shoulder stock is in an unfolded position when it does not rest against the outer lateral surfaces of the frame, but rather forms an extension of the frame in the longitudinal direction thereof. The unfolded shoulder stock is fixed in the unfolded position by the locking mechanism. In the unfolded position, the pistol with the unfolded shoulder stock can be pulled against and fixed on the shoulder such that the precision and accuracy for a precise shot are enhanced. The locking mechanism can be actuated and thereby disengaged such that the shoulder stock can be folded and subsequently placed against the left or the right outer lateral surface of the frame depending on the design of the hinge.
In another embodiment of the invention, the pistol comprises a locking device extending in the longitudinal direction of the frame on at least one of the outer lateral surfaces of the frame. The locking device comprises a catch element or an engaging element and a movably mounted actuating element, which cooperates with the shoulder stock and particularly locks the shoulder stock on at least one of the outer lateral surfaces of the frame in the folded position. Depending on the design of the locking device, this locking device comprises, for example, the catch element and the movably mounted actuating element and the shoulder stock accordingly comprises the associated engaging element. The locking device may also be realized in such a way that this locking device comprises the engaging element and the movably mounted actuating element and the shoulder stock comprises the corresponding catch element.
The function of the locking device in connection with the shoulder stock is described below with reference to the exemplary design, in which the locking device comprises the catch element and the movably mounted actuating element. However, this does not represent any technical or functional limitation of the locking device. The exemplary embodiment, in which the locking device comprises the engaging element and the movably mounted actuating element, is based on the same functional principle. In this respect, the mechanical components are simply used in an interchanged manner.
In addition, the locking device may have an integral design, in which the catch element and the actuating element are realized in one piece.
When the shoulder stock is pivoted from the unfolded position into the folded position toward the right or toward the left outer lateral surface of the frame, the catch element of the locking device is received by the engaging element of the shoulder stock and the folded shoulder stock is locked on the right or the left outer lateral surface of the frame in the folded position.
In an embodiment of the invention, the engaging element is realized in the form of a lead-through extending from one outer lateral surface to the other outer lateral surface of the shoulder stock. However, the shape of the lead-through is not limited to the shape illustrated in the figures. In fact, the lead-through may also be realized, for example, in the form of a square, circular or oval lead-through. The lead-through of the engaging element is arranged in front of the beginning of the end piece of the shoulder stock, which is placed against the shoulder when a shot is fired, in such a way that the catch element of the locking device is received by the engaging element of the folded shoulder stock. The engaging element has a beveled lead-through side on the side of the lead-through lying closest to the holding device. The bevel extends in such a way that the length of the shoulder stock from the holding device up to the edge of the bevel, which rests on the outer lateral side of the pistol frame in the folded position of the shoulder stock, is shorter than the length of the shoulder stock from the holding device up to the edge of the bevel, which does not rest on the outer lateral side of the pistol frame in the folded position of the shoulder stock.
At this point, it should be noted that the design of the engaging element is not limited to the above-described embodiment. In fact, the engaging element may also be realized in the form of a recess in the shoulder stock with a corresponding receptacle for the catch element. Furthermore, the engaging element may also be realized in the form of a hook element that is received and/or locked by a catch element, which is realized with a shape corresponding to that of the hook element.
Furthermore, the catch element may be realized, for example, in the form of a hook and connected to the movably mounted actuating element. However, the design of the catch element is not limited to the shape illustrated in the figures. In fact, different shapes of the catch element can also be used. The movably mounted actuating element extends in the longitudinal direction of the frame and, when actuated, moves in the direction of the front end position until it ends flush with the front end position. When the movably mounted actuating element is not actuated, the catch element and the engaging element are connected to one another in such a way that the locking mechanism cannot be disengaged without application of an increased force upon the end piece of the shoulder stock and the shoulder stock cannot be moved into the unfolded position. In this case, the catch element is in the catch position. When the movably mounted actuating element is actuated, the catch element is moved in the direction of the front end position and therefore into a centered position relative to the engaging element, which corresponds to the release position, such that the catch element is no longer in contact with the engaging element and the locking mechanism of the shoulder stock can be disengaged.
In another embodiment, the shoulder stock can be disengaged from the locking mechanism by applying an increased force and moved from the folded position into the unfolded position. Applying an increased force refers to the application of a force, which is exerted in the direction of the unfolded position of the shoulder stock by pulling on the end piece of the shoulder stock and greater than the force required for moving the shoulder stock into the unfolded position when the locking device is actuated. The locking mechanism for the shoulder stock in the folded position is disengaged by pulling on the end piece of the shoulder stock with an increased force. The disengagement of the locking device under the application of an increased force advantageously serves as an emergency function in situations, in which the actuating element malfunctions and/or is damaged.
The movably mounted actuating element is moved in the direction of the front end position, for example, with the trigger finger of the user such that the locking mechanism is disengaged and the shoulder stock is released. After the locking mechanism has been disengaged with the trigger finger of the user, the actuating element is moved from the direction of the front end position into the position, in which locking Of the shoulder stock takes place, e.g. by means of a spring mechanism.
The catch element furthermore has a bevel that corresponds to the bevel of the lead-through of the engaging element. In this way, an enhanced reception and sliding motion of the catch element into the engaging element is advantageously achieved when the shoulder stock is locked in the folded position. In the folded position, the bevel of the catch element exerts a force upon the bevel of the engaging element such that the actuating element moves in the direction of the front end position against the force effect of the spring mechanism to such an extent that the catch element is in a centered position relative to the engaging element (release position), wherein the catch element is thereby completely received by the engaging element and the actuating element is moved opposite to the front end position by the spring mechanism and thereby blocks the catch element in the engaging element (catch position) such that the shoulder stock is locked in the folded position.
In another embodiment, the pistol comprises a spring-loaded pressure element on at least one of the outer lateral surfaces of the holding device, which corresponds to the pivoting motion of the hinge. In the folded position of the shoulder stock, the locked shoulder stock presses the spring-loaded pressure element into a correspondingly provided receptacle against the force of the spring mechanism of the pressure element such that the spring mechanism generates and exerts a force upon the shoulder stock.
When the actuating element is actuated by the user of the pistol in order to unfold the shoulder stock, the force effect of the spring mechanism of the pressure element causes a pivoting motion of the shoulder stock out of the folded position. For example, this pivoting motion refers to the formation of a gap between the lateral surface of the frame and the shoulder stock, wherein said gap has such a size that the shoulder stock can be taken hold of with the fingers through the gap and pivoted into the unfolded position.
The movably mounted actuating element and the spring-loaded pressure element advantageously improve and enhance the safety and the manipulation of the pistol and also ensure safer and faster handling thereof. Due to the pivoting motion of the shoulder stock from the folded position and the formation of a gap upon the actuation of the actuating element, the user of the pistol can conveniently reach between the pistol and the shoulder stock in order to additionally move the shoulder stock into the unfolded position without having to elaborately pull on the end piece of the shoulder stock. Pulling on the end piece of the shoulder stock would require the hand to move very close to the muzzle of the pistol and therefore could lead to injuries.
It is furthermore advantageous that the user of the pistol can keep holding the pistol in the firing position or aimed at a target while the shoulder stock is pivoted and moved into the unfolded position with the fingers of the free hand. Due to the pivoting motion of the shoulder stock, the pistol is prevented from tilting or losing its aim when the shoulder stock is unfolded, wherein this can lead to improved reaction time and accuracy.
It is furthermore advantageous that the hinge in the receiving device for realizing the pivoting motion of the shoulder stock can have a correspondingly simpler technical design because it is no longer used or technically required for the locking mechanism in this embodiment. This reduces the cost and the technical complexity of the hinge, as well as its design. Furthermore, the servicing expenditures arising due to wear phenomena of the hinge caused by folding and unfolding the shoulder stock are advantageously reduced.
In another embodiment of the holding device, this holding device comprises a guiding means such that the shoulder stock can be extended from at least one position near the frame. In this context, extending refers to the option of moving the shoulder stock from a first position, in which the pistol can be used without shoulder stock, into a second position, in which the pistol can be placed against the shoulder. In the first position, for example, two separate guide arms of the shoulder stock rest against the respective outer lateral surfaces. Alternatively, the shoulder stock may also be realized with only one guide arm. In the retracted position, the end piece of the shoulder stock, which is placed against the shoulder when a shot is fired, rests against the holding device. With respect to its function, this position corresponds to the folded position of the shoulder stock. In the second position, the shoulder stock is extended and the end of the guide arm or the ends of the two separate guide arms respectively locks or lock in the guiding means of the holding device. The frame of the pistol is extended by the length of the guide arms of the shoulder stock. The pistol can be placed against the shoulder with the shoulder stock. This position of the holding device corresponds to the unfolded position of the shoulder stock. The guide arms do not protrude beyond the length of the pistol in the first position. In an embodiment, the guiding means may be realized in the form of a telescope. In this way, the retracted shoulder stock has an even shorter length.
In addition, catch means may be provided in the holding device and at least one guide arm, wherein said catch means define a predefined positioning of the shoulder stock and thereby ensure that the shoulder stock assumes the correct position, particularly in the extended configuration, during fast operation by the user.
The holding device of the pistol is designed in such a way that the shoulder stock fixed in the holding device has a downward slope relative to the longitudinal extent of the frame. This downward slope defines the height difference between the shaft height and the sighting line. It is therefore ensured that—when the pistol is fixed on the shoulder by means of the shoulder stock—the sighting line and the line of sight correspond despite fixing the pistol on the shoulder.
In another embodiment of the receiving device, this receiving device comprises a sighting mechanism that is connected to the receiving device by means of a holding device. For example, this sighting mechanism may be a light dot sighting mechanism, wherein the holding device is designed in such a way that it can also be used for sighting mechanisms of different types and manufacturers.
In another embodiment, the receiving device and the carriage are covered by the sighting mechanism in the rear end position and potential contact with the carriage and therefore an injury due to the backward motion of the carriage are prevented. In an embodiment without sighting mechanism, i.e. with a mere mechanical notch and bead sighting mechanism, the open region of the receiving device can be covered by means of a cover structure. This cover structure may be made of the same material as the receiving device; however, it is also possible to use any other material that meets weapons manufacturing requirements. This cover structure may be attached positively and/or non-positively.
In an embodiment, the holding device comprises on its upper side a Picatinny rail that can be used for attaching accessories and/or add-on parts with a Picatinny interface.
In another embodiment, the pistol comprises on the underside of the frame a Picatinny rail that extends in the longitudinal direction of the frame from the front end position to the trigger.
A Picatinny rail is a rail according to NATO standards for mounting accessories on firearms quickly and with a high degree of repeat accuracy. The Picatinny rail—also known as NATO Accessory Rail (NAR)—is officially referred to as MIL-STD-1913 and was standardized by NATO with this specification under STANAG 2324 (Standardization Agreement).
In an embodiment of the invention, the pistol comprises a groove or rail extending in the longitudinal direction of the frame on at least one of the outer lateral surfaces of the frame, wherein said groove or rail preferably serves for being received in a guide of a holster. The at least one groove or rail guides the pistol during its insertion into the holster and its removal from the holster such that tilting and jamming of the pistol are prevented.
The grooves or rails arranged in the frame have the advantage that the pistol can be smoothly guided and/or stored in the holster regardless of its remaining exterior geometry. With respect to the guidance and storage of the pistol in the holster, it is now particularly irrelevant, for example, whether a tactical lamp is mounted on the Picatinny rail.
In an embodiment of the invention, the extension of the frame is chosen in such a way that an ergonomically suitable length of the shoulder stock (measured from the grip) is on the one hand achieved and the folded shoulder stock on the other hand does not protrude beyond the front end of the weapon.

FIG. 1 shows a first embodiment of the pistol 1 according to the present invention. The pistol 1 comprises a frame 2. On its upper side, the frame 2 comprises a carriage guide 5 that extends in the longitudinal direction and serves for at least partially receiving and/or guiding a carriage 8 and a barrel 9. The carriage 8 moves in the carriage guide 5 during loading processes and when the carriage 8 is manually displaced from a front end position 11 into a rear end position 12. The trigger 3, which can be actuated by the user in order to fire a shot, is movable relative to the frame. The frame 2 furthermore contains a grip 6, wherein the frame and the grip may be realized in one piece or separately. The magazine well 10 is recessed into the grip 6. FIG. 1 shows an embodiment of the pistol 1, in which a magazine is inserted into the magazine well 10.
The carriage 8 at least partially receives the barrel 9 with the cartridge chamber in its interior. In FIG. 1, the barrel 9 is longer than the carriage 8. For example, a (not-shown) silencer can thereby be advantageously attached in this embodiment. The pistol 1 also comprises a Picatinny rail 21, which extends on the underside in the longitudinal direction of the frame 2 from the front end position 11 to the trigger 3. The Picatinny rail 21 is provided for attaching add-on parts such as, for example, a tactical light, an additional grip and/or a laser targeting device. The carriage 8 furthermore comprises an actuating section 20 that extends on the outer lateral surfaces of the carriage 8. The actuating section 20 advantageously makes it possible to take hold of the carriage 8 with the hand in a non-slip manner and to thereby manually displace the carriage 8 in the carriage guide 5 from the front end position 11 into the rear end position 12 or to manually move the carriage 8 in the carriage guide 5 from the rear end position 12 into the front end position 11. In addition, the frame 2 comprises a longitudinally extending groove or rail 23 on the outer lateral surface. This groove or rail 23 receives a (not-shown) strip or rail integrated into a holster such that the pistol 1 is guided during its removal from and insertion into the holster and tilting and jamming are prevented.
The frame 2 comprises the receiving device 13. The receiving device 13 extends in the longitudinal direction of the frame 2 and receives the carriage 8 in the rear end position 12. The receiving device 13 is covered by the holding device 18. A sighting mechanism 19 in the form of an exemplary light dot sighting mechanism is illustrated in FIG. 1. The sighting mechanism 19 is connected to the receiving device 13 by means of the holding device 18. The sighting mechanism 19 can be released and removed by disengaging the holding device 18.
In addition, the receiving device 13 comprises the holding device 14 for receiving the shoulder stock 15. The shoulder stock 15 advantageously has a downward slope S such that the sighting line of the pistol 1 and the line of sight of the user are matched despite fixing the pistol 1 on the shoulder by means of the shoulder stock 15. The downward slope improves the body posture and the way the pistol 1 is held on the shoulder.
FIG. 2 shows a top view of an embodiment of the pistol 1 with unfolded shoulder stock 15. This embodiment has the characteristics of the embodiment of the pistol 1 described above with reference to FIG. 1. The shoulder stock 15 is connected to the receiving device by means of the holding device 14. The holding device 14 comprises a hinge 17 for connecting the shoulder stock 15 in a pivotable manner. Due to the pivotable connection, the shoulder stock can be pivoted toward the right or the left outer lateral surface of the frame depending on the design of the hinge and therefore placed against the respective outer lateral surface of the frame. In the embodiment according to FIG. 2, the shoulder stock can be pivoted toward the right outer lateral surface of the frame 2. The shoulder stock 15 is fixed in the unfolded position by the locking mechanism 16. The shoulder stock is released by actuating the locking mechanism 16 such that the shoulder stock 15 can in this embodiment be pivoted toward and placed against the right outer lateral surface of the frame 2. According to a particularly preferred embodiment, the shoulder stock can be locked in the folded position, as well as in the unfolded position.
FIG. 3 shows a left side view of an embodiment of the pistol 1 with unfolded shoulder stock 15. In this embodiment, the frame 2 comprises the carriage catch lever 4 on the left outer lateral surface. The carriage catch lever 4 locks the carriage 8 in the rear end position 12 upon its actuation. The frame 2 furthermore comprises a groove 23 that extends in the longitudinal direction on the outer lateral surface. This groove 23 receives a (not-shown) strip or rail integrated into a holster such that the pistol 1 is guided during its removal from and insertion into the holster and tilting and jamming of the pistol 1 are prevented.
According to another preferred embodiment, the arrangement of the groove or rail may also be interchanged with respect to the allocation to the pistol or the holster such that the pistol comprises the rail and the holster comprises the groove.
The carriage 8 furthermore comprises an actuating section 20 that extends on the outer lateral surfaces of the carriage 8. This actuating section corresponds to the dimensions illustrated on the right side of the pistol 1 (see FIG. 1).
FIG. 3 furthermore shows the receiving device 13 for receiving the shoulder stock 15 by means of the holding device 14 and for receiving the sighting mechanism 19 by means of the holding device 18. The receiving device 13 receives the carriage 8 in the rear end position 12. The receiving device 13 is covered by the sighting mechanism 19. The sighting mechanism 19 can be released and removed by disengaging the holding device 18.
FIG. 4 shows a right side view of an embodiment of the pistol 1 with folded shoulder stock 15. This embodiment has the characteristics of the embodiment of the pistol 1 described above with reference to FIG. 1. In this embodiment of the pistol 1, the shoulder stock 15 is folded toward and placed against the right outer lateral surface of the frame 2.
FIG. 5 shows a rear view of an embodiment of the pistol 1 with folded shoulder stock 15. The receiving device 13 comprises the holding device 14 that receives and connects the shoulder stock 15 to the receiving device 13. The holding device 14 comprises the locking mechanism 16 that fixes the shoulder stock 15 in the unfolded position. The shoulder stock 15 can be pivoted about the hinge 17 and unfolded toward the longitudinal direction of the frame 2. The shoulder stock 15 is fixed in the unfolded position by means of the locking mechanism 16 and can only be folded again by manually actuating the locking mechanism 16.
FIG. 6 shows a top view of an embodiment of the pistol 1 with folded shoulder stock 15. The fixed shoulder stock 15 can be released from the unfolded position by actuating the locking mechanism 16 such that the shoulder stock 15 can be folded about the hinge 17, in this embodiment against the right side of the pistol 1.
FIG. 7 shows a right side view of an embodiment of the pistol 1 with unfolded shoulder stock 15 and without sighting mechanism 19. In this embodiment, the receiving device 12 is illustrated in the form of a retrofit set without sighting mechanism 19. The receiving device 12 extends the frame 2 in the longitudinal direction and receives the carriage 8 during the motion from the front end position 11 into the rear end position 12. In this embodiment, the pistol is aimed by means of the mechanical sighting mechanism, i.e. the notch 26 and the bead 25. Since the carriage 8 is received in the rear end position 12, it is furthermore ensured that the user is protected against injuries during the backward motion of the carriage 8 into the rear end position 12. The retrofit set in the form of an adapter represents an economical alternative to the new purchase of a pistol 1 with a one-piece design of the frame 2 and the receiving device 13.
