The invention relates to a cartridge magazine intended for a handgun for a handgun, the cartridge magazine having:

• a housing for a cartridge magazine for a handgun, which extends along an X-axis, a Y-axis and a Z-axis and in its interior forms an interior with a first and a second area,
• wherein a transition area is formed between the first and the second area which connects the first and the second area to one another,
• the interior space being delimited by the inner surfaces of a front wall, a rear wall, a first side wall and a second side wall, the inner surface of the front wall extending in the direction of the Z-axis in at least one area along a first circular path,
• wherein the inner surface of the rear wall extends in at least one area in the direction of the Z-axis along a second circular path,
• and wherein the inner surfaces of the front wall and the rear wall are at a distance A from one another in this at least one region, the cartridge magazine further having a bottom cover which is suitable for at least largely closing an at least partially open bottom side of the housing, a first and a second Has feeder, which are designed such that the second feeder is at least partially movable into the space of the first feeder, a first spring that between the first feeder and the bottom cover is arranged and a second spring which is arranged between the first and the second feeder.

The invention further relates to a method of operating a handgun using a cartridge magazine.

Cartridge magazines for handguns have been known for a long time and are manufactured in various designs according to the state of the art. The person skilled in the art first distinguishes between cartridge magazines that are permanently connected to the handgun and those that can be quickly and repeatedly connected to the handgun by releasing a holding mechanism. Among the last-mentioned cartridge magazines, which are then also called cartridge insertion magazines, drum magazines and row magazines are known above all. The cartridge magazine on which the invention is based in its various configurations relates in particular to such a series magazine. The cartridges are stored in a row magazine in such a way that when the cartridge magazine is at least partially filled, they touch one another tangentially on their case walls within the housing of the cartridge magazine. Depending on whether the row magazine is designed in one or more rows, the points of contact or the lines of contact between the cartridges move with one another.

In particular for official purposes, but also in the field of sporting use, it is often desirable to equip a handgun with a high level of firepower by providing a suitable cartridge magazine. This means the ability to fire a large number of shots within a short period of time. Since changing a cartridge magazine, depending on the design of the holding mechanism and the skill of the operator, takes a certain amount of time - for example 2 to 4 seconds - efforts are made to make the capacity of an individual cartridge magazine as large as possible.

This contrasts with the manageability of the cartridge magazine for the operator, who has to be able to carry the cartridge magazine with him outside of the handgun - as a replacement magazine - that has to help the operator manage a magazine change even in stressful situations and the manageability of the handgun with the cartridge magazine inserted if possible not or at least as little as possible.

A handgun that has been used by the authorities around the world for several decades is a self-loading rifle of the AR - 15 / A 16 model. For the repeatable, detachable connection of cartridge magazines with the handgun, this weapon has a magazine shaft that is open at the bottom and into which suitable cartridge magazines can be inserted. For this purpose, cartridge magazines with different capacities are known. To operate this model of weapon or handguns of the same class, magazines with a capacity of 20 or 30 cartridges are common today. A handgun of the same generic type is understood to mean a self-loading rifle which offers the operator a choice between a first mode in which the weapon can be operated in such a way that a single shot is always triggered by pressing its trigger once and a second mode in which the Weapon can be operated in such a way that a number of shots are always triggered by pressing its trigger once. In connection with the present description, the generic equality of the handgun described should also be preserved if the operator, when selecting a plurality of shots to be fired, additionally between the firing of a closed group of shots, for example 3- or 5-shot bursts or a Can choose continuous fire.

How quickly the shots are fired one after the other by the handgun when an automatic sequence of fire is selected after only pulling the trigger is called cadence. The cadence of a handgun of the type described that is customary today is generally between 600 rounds per minute and approx. 1200 rounds per minute.

Assuming an average rate of 900 rounds per minute, a 20 round magazine is emptied in 1.33 seconds. A 30 round magazine, on the other hand, already lasts for exactly 2 seconds. Assuming that a magazine change can be completed in 3 seconds even under operational conditions, the handgun achieves an operational effectiveness of approx. 40%.

With a 60 round magazine, on the other hand, under otherwise identical conditions, it achieves an operational effectiveness of approx. 58% and thus experiences an increase of almost 50%.

Unfortunately, for various reasons, the experience gained in the construction of cartridge magazines with 20 or 30 rounds can only be transferred to a very limited extent to the construction of such high-capacity magazines with, for example, 60 rounds. Despite the long-recognized need for high-capacity in-line magazines, high-capacity magazines are now almost exclusively offered as drum magazines. However, drum magazines are a great disadvantage for the operator when it comes to carrying and handling the handgun when operating.

From the US 8,061,071 B2 a cartridge magazine in the form of a series magazine is now known that has a capacity of 60 cartridges. Such a magazine significantly increases the effectiveness of a handgun belonging to it compared to the 20 or 30-round magazines, since a magazine change, during which the handgun is not operational and during which its operator is also defenseless, is only necessary after twice or three times as long duration of use .

US3226869 A is aimed at a similar purpose (holding four rows of cartridges arranged directly next to one another in the first area), but with a right-hand magazine shape and a different feed system.

It is the object of the invention to find an alternative to that from US3226869 A to provide known housing for a cartridge magazine and the cartridge magazine disclosed there.

In addition, various disadvantages have been shown in use with prolonged use of the housing and the magazine. The cartridge magazine is also movably arranged due to the large number of inside the magazine housing Individual parts are increasingly susceptible to dirt, wear and tear and failure. In addition, the case can only withstand pressure on the inner side surfaces to a limited extent. Therefore, it is a particular object of the invention to overcome these and other disadvantages.

Those related to the US 8,061,071 B2 The discussion conducted essentially also applies to the cartridge magazines according to the prior art, which are also known from the prior art WO2011 / 159383 A and the U.S. 4,589,218 A , because both magazines also divide the individual rows of cartridges to be stored in the four-row area into two separate double rows and thus prevent a trouble-free function sequence with an uninterrupted, defined support of the cartridges among one another.

At least some of the objects are achieved in a cartridge magazine of the type mentioned in that the first area is designed to accommodate four rows of cartridges arranged directly next to one another and preferably offset from one another in the Z direction, and the second area is designed to accommodate two directly rows of cartridges arranged next to one another and preferably offset from one another in the Z direction.

Because the rows of cartridges are arranged directly next to one another in the first area as in the second area, the housing can be designed to be particularly slim, which greatly improves the handling of a cartridge magazine comprising such a housing.

The cartridges are arranged directly to one another because they are in direct contact with one another, at least in some areas of their lateral surfaces. Since with a cartridge magazine for a handgun only one cartridge is removed from the magazine lips during the loading process, the cartridges must be arranged in such a way that always only a single cartridge can rest with its outer surface on at least one of the two magazine lips. So if one area has a space for more cartridge rows than another area, the individual cartridges in the cartridge rows must be located in the Between them arranged transition area (intermediate area) when reducing the cartridge rows roll in a zipper system on their outer surfaces one below the other. However, if a partition is provided, this process will be disrupted. As a result, individual cartridges are transported at different speeds in the direction of the magazine lips. There are even real jumps in speed. Individual cartridges temporarily lose control of their neighboring cartridges. When the cartridges slide later, the outer surfaces of the cartridges hit each other. Such processes are difficult to calculate and can, in particular in a high-frequency operation of a handgun, significantly increase their susceptibility to failure. A cartridge magazine having an intermediate wall is not suitable for providing a repetitive movement process of the cartridges it contains as they move in the direction of the magazine lips and is therefore only of limited use. In that, according to the invention, the first area is designed to accommodate four rows of cartridges arranged directly next to one another and preferably offset from one another in the Z direction, and the second area to accommodate two rows of cartridges arranged directly next to one another and preferably offset from one another in the Z direction Cartridges is formed, a repeatable movement process of all the cartridges located in the magazine and removed one after the other from the magazine lips during operation is ensured. A smooth rolling of the cartridges on their outer surfaces is therefore ensured.

Since the lack of impacts on the outer surfaces of the cartridges also leads to considerably lower transverse forces acting on the side surfaces from the inside, it has surprisingly been shown that the wall thicknesses of a housing according to the invention for a cartridge magazine are not significantly different from the wall thicknesses of conventional ones Must distinguish between cartridge magazines and their housings with a significantly lower capacity.

In order to ensure a trouble-free and repeatable process sequence during operation during the gradual ascent of the cartridges in the interior of the cartridge magazine, it is particularly advantageous that the cartridges P in all areas of the housing are arranged directly adjacent to one another.

It is advantageous if the cartridge magazine has a locking piece which is movably arranged with respect to the housing of the cartridge magazine and which can be moved by the feeder, which can be moved through the second area, into a free space arranged in the housing in the rear wall between the magazine lips.

The locking piece is advantageously suitable for limiting the freedom of movement of the breech of a handgun. Furthermore, the spear piece is advantageously formed by a bent piece of sheet metal that is arranged so as to be supported and movable on the inside and the outside of the rear wall. The bent piece of sheet metal is then made, in particular, of tempered spring steel with great advantage. It is also advantageous if the piece of sheet metal has an angle of about 90 degrees between two angles of about 180 degrees.

It goes without saying that a cartridge magazine according to the invention can advantageously be designed with the advantageous design features of the housing for the cartridge magazine. With regard to an economic description and in order to avoid repetition, the design options and their advantages for both objects are described below either on the basis of the housing or on the basis of the cartridge magazine. Even if the respective other subject matter is not mentioned, the person skilled in the art knows that the advantages described in connection can also be transferred to the respective other subject matter of the invention.

In an advantageous embodiment, the inner surface of the front wall of the housing of the cartridge magazine has a first projection which protrudes in the direction of the X-axis into the interior of the housing and extends along the Z-axis starting from the intermediate area at least partially into the first area and at least partially also extends the second region, and has the inner surface of the rear wall has a second projection which protrudes into the interior of the housing in the direction of the X-axis and has a beginning in the first area and an end in the intermediate area along the Z-axis.

In this way, the order between the individual cartridges to be accommodated in the housing of the cartridge magazine can be improved. The position of the cartridges in the rear area can be spread somewhat through the second projection, so that they can be easily aligned with one another in their front area. This improves the integration behavior of the individual cartridges with one another while reducing the number of cartridge rows formed from them in the magazine. The effect is particularly strong if the cartridges have a bottle-shaped case / a bottle-shaped case jacket. Both the first projection and the second projection are suitable for guiding the feeder (s) of a cartridge magazine and, not least, contribute significantly to the stability of the housing.

The inner surfaces of the first side wall and the second side wall in the first area and in the second area are preferably arranged essentially parallel to one another and a virtual central plane is formed between them in the X and Z directions in the Y direction.

In this way, a process of the cartridge movement within the housing / cartridge magazine that is precisely repeated during operation is additionally supported.

It can furthermore be advantageous if the inner surfaces of the first side wall and the second side wall are at a distance B from one another in the first region and a distance C from one another in the second region.

It is of great advantage if the distance B is 1.85 to 2.15 times, in particular 1.95 to 2.05 times, the distance C.

In this way, the interior of the cartridge magazine is used particularly well so that the external dimensions can also be designed to be particularly compact. In addition, the cartridges in the first area assume a similar position to one another as in the second area, which can once again significantly increase the functional reliability of the handgun operated with a cartridge magazine designed in this way.

It is preferred that the cross section of the first area extending along the X-axis and the Y-axis is divided into a rectangular zone and a trapezoidal zone adjoining the rectangular zone, and that the cross-section extending along the X- Axis and the Y-axis extending, cross section of the second area divided into a rectangular zone and a trapezoidal zone adjoining the rectangular zone.

In this way, the stability of the housing of the cartridge magazine is increased.

In addition, the aforementioned effects, for example the enforcement of a slight inclination of the cartridges located in the cartridge magazine with respect to one another by means of the housing of the cartridge magazine, can thereby be supported. Furthermore, such a cross section is also particularly suitable for cartridges with bottle-shaped silhouettes.

The handling of the cartridge magazine can also be improved in this way if the external shape of the housing of the cartridge magazine is based on this cross section.

In such a configuration, the distance b and C each relates to the distance between the inner surfaces of the side walls in the rectangular zone.

It is ensured with great advantage that the first projection is arranged at least in sections within the central plane and / or the second projection is arranged at least in sections within the central plane.

The stability of the housing is increased in a particularly simple manner. In addition, such a configuration promotes a trouble-free process when the cartridges are regrouped from a four-row arrangement to a two-row arrangement within the cartridge magazine.

It is also preferred that the extension of the first projection in the X direction is between 5% of A and 18% of A and very particularly between 8% of A and 13% of A.
and / or the extension of the second projection in the X direction is between 5% of A and 18% of A and very particularly between 8% of A and 13% of A.

The projections therefore face one another in the interior of the cartridge magazine.

In tests, these values have surprisingly achieved particularly good results with regard to the functional reliability of the cartridge magazine and a handgun operated with a cartridge magazine designed in this way, as well as the stability of the housing of the cartridge magazine.

Furthermore, cartridge magazines designed in this way proved to be particularly resistant to soiling and were able to maintain their full functional reliability even under extreme soiling.

Purely by way of example, the above-mentioned ratios are to be explained better once again using a numerical example that is not to be considered conclusively. At a distance A of 58 mm, the extent of the first projection in the X direction is therefore, for example, between 3.0 mm and 10.0 mm and very particularly between 5.0 mm and 8.0 mm
and / or the extension of the second projection in the X direction is, for example, between 3.0 mm and 10.0 mm and very particularly between 5.0 mm and 8.0 mm. The distance A can assume any value between 18.0 mm and 130 mm, a value between 30.0 mm and 90.0 mm being preferred.

The inner surface of the rear wall preferably has two grooves in at least one area, each of which runs laterally, preferably directly, adjacent to the second projection.

In this way, a particularly stable guidance of a feeder can be made possible if the feeder is shaped accordingly. In addition, such a configuration increases the dirt resistance of the cartridge magazine.

For this purpose, the extent of the two grooves in the X direction can be, for example, between 2% of A and 9% of A, in particular between 3% of A and 8% of A and very particularly between 4% of A and 6% of A. Surprisingly, material recesses in this area even increase the rigidity of the cartridge magazine.

It is advantageous if the inner surface of the first side wall has a projection which protrudes in the direction of the Y-axis into the interior of the housing of the cartridge magazine and has a beginning in the first area and an end in the intermediate area along the Z-axis and / or if the inner surface of the second side wall has a projection which protrudes in the direction of the Y-axis into the interior of the housing and has a beginning in the first area and an end in the intermediate area or in the second area along the Z-axis.

In this way, the cartridge feeder (s) and / or the cartridges can also be guided laterally, which further reduces the risk of a misalignment of the cartridge and / or cartridge feeder and a possible malfunction of the cartridge magazine resulting therefrom. In addition, such projections increase the rigidity and stability of the housing.

An important advantage also results from the fact that the cartridges are then guided with very little friction on the relatively narrow front areas of the projections. In addition, the frictional resistance that the cartridges and / or the Cartridge feeders on their way with the main direction along the Z-axis and towards the magazine lips with a practically clean cartridge magazine to a very heavily soiled cartridge magazine always remain approximately identical, so that the desired repeatability can be maintained in the operation of the handgun regardless of the degree of soiling.

It can be of additional advantage if the protrusion or protrusions is / are arranged in a border area between the rectangular zone and the trapezoidal zone of the cross section of the first area adjoining the rectangular zone.

Surprisingly, it has been shown that it is advantageous to support the cartridge feeder or cartridges and / or cartridges laterally, preferably only by a single projection, it being advantageous if the projection from the inner surface of the rear wall is at a distance of about 0, 65 times distance A to 0.85 times distance A

An advantageous embodiment results when the inner surface of the first side wall is formed in the intermediate area along a first curved path and the inner surface of the second side wall in the intermediate area along a second curved path, the curved paths each comprising a turning point and extending from the bottom of the housing to the top of the housing in front of the respective Turning point extend in the direction of the central plane and, behind the respective turning point, cling to a first and a second parallel to the central plane.

In this way, a particularly gentle way of guiding cartridges and / or cartridge feeders is achieved. This contributes significantly to stable, that is, defined and repeatable operation.

It can be particularly advantageous if the curved paths are designed to be mirror-symmetrical.

This does justice to a symmetrically constructed cartridge particularly well.

It can also or in addition be advantageous if the first and second cam tracks are arranged offset from one another by an offset V in the Z direction.

This promotes trouble-free regrouping of the cartridges with one another particularly well.

It is preferred that the offset V is between 7% and 35%, in particular between 10% and 25% and very particularly between 18% and 22% of the difference between distance B and distance C.

Tests have shown, surprisingly, that an offset within the specified range of values promotes particularly trouble-free operation.

The housing of the cartridge magazine is made in one piece with great advantage.

In this way, the stability of the cartridge magazine becomes significant. In addition, inner and outer surfaces can be designed freely and annoying material overlaps can be avoided.

The housing of the cartridge magazine is preferably made of a homogeneous material, in particular the structure of the material being of the same design over the entire housing.

Embrittlement, for example through welds, can also be avoided.

In the context of the present document, the material structure is also designed in the same way when the material is a reinforced material.

It is particularly advantageous if the housing of the cartridge magazine is made of plastic.

In this way, particularly light and resistant cartridge magazines can be formed. A polyamide (PA), in particular a reinforced polyamide or a polyetheretherketone (PEEK), is preferably used.

In order to be able to achieve particularly inexpensive production, for example for so-called “single-use cartridge magazines”, a polyethylene (PE) can also be used, for example.

In a method for operating a handgun using a cartridge magazine, at least part of the object (s) on which the invention is based is achieved in that a cartridge magazine according to one of claims 1 to 18 is used when operating the handgun.

The advantages resulting from this and from the use of advantageous embodiments of the invention have already been described in connection with the cartridge magazine according to the invention and apply accordingly here.

In the following, a preferred embodiment of the invention is explained in more detail with reference to the figures of a single drawing. The description of the preferred embodiment is by no means to be regarded as conclusive.

Show it:

Figure 1:

A side view of a cartridge magazine according to the invention

Figure 2:

A front view of the in Figure 1 illustrated cartridge magazine

Figure 3:

A rear view of the in Figure 1 and 2 illustrated cartridge magazine

Figure 4:

A corresponding sectional side view

Figure 5:

A rear view of the cartridge magazine in a sectional view and in the state partially filled with cartridges

Figure 6:

The housing cross-section of the cartridge magazine in area I.

The drawing with the Figures 1 to 6 shows a preferred embodiment of a cartridge magazine 2 according to the invention, which comprises a housing 1.

The same components are named the same in all figures and do not have to be represented or visible in all figures or be described again in all figures.

In the drawing shows Figure 1 , the cartridge magazine 2 in a side view from the outside. The front wall 3, the rear wall 4 and the first side wall 5 of the housing 1 are clearly visible. A base cover 25 is fixed on the underside of the housing 7. This can for example be pushed on from the front wall 3 in the direction of the rear wall 4 in, in the housing 1 provided guide grooves and for example by an in Figure 4 shown inner base plate by pressure at least the also in Figure 4 first spring 28 shown to be secured against loss.

It can also be seen that the inside 3a of the front wall 3 at least in one, in Figure 2 and Figure 5 designated area I, II or III runs along a first circular path K1. In the example shown, at least the inside 3a of the front wall 3 should even lie on the first circular path K1 in all areas I, II and III. At a distance A from this, the inside 4a of the rear side 4 runs in at least one area, I, II or III, along a second circular path, the radius of the second circular path K2 being greater by A than the radius of the first circular path K1. In the example shown, at least the inside 4a of the rear wall 4 should even lie on the first circular path K2 in all areas I, II and III. The housing 1 of the cartridge magazine has on its housing top 8 magazine lips 9 which are designed for this purpose, in an at least partially filled state of the cartridge magazine, the topmost in the interior IR (cf. Figure 4 and Figure 6 ) of the cartridge magazine 2 located cartridge P to support on its outer surface. In the at least partially filled state, the at least one cartridge P is pressed against the inside of the magazine lip 14 by means of spring force, in particular a spring force resulting from a first spring 28 and a second spring 29, and can then, when a handgun (not shown) is in operation, move forward from its breech, so in the direction of the front wall and over it can also be removed from the cartridge magazine 2. The top of the housing 8 is via the in Figure 2 Clearly visible formation of the two magazine lips 14 is not closed any further, but rather open.

Next is in the in Figure 2 The illustrated outer front view of the cartridge magazine 2, in addition to the first side wall 5, also shows the second side wall 6 of the housing 1. The position of the first area I and the second area II, as well as the intermediate area III connecting them, can also be seen. The locking area 30 arranged in the area 2 is designed to form a mechanism for releasably fixing the cartridge magazine in the handgun intended for this purpose, but not shown here, with a corresponding counterpart on the handgun side.

Figure 3 shows a rear view of the cartridge magazine 2, the rear wall 4 being clearly visible. The central plane runs through the longitudinal axis of the magazine in the Z direction, which in connection with the description of the preferred exemplary embodiment is only shown in FIG Figure 3 and 6th is shown how other planes and components not shown or visible in other figures but are present in all figures of the embodiment example shown only in the drawing.

Next shows Figure 3 a cartridge magazine 2 with a locking piece 32 which is movably arranged opposite the housing 1 of the cartridge magazine 2 along the illustrated double arrow, which from the feeder movable through the second area II into a free space 33 arranged in the housing 1 in the rear wall 4 between the magazine lips 14, is movable.

The locking piece 32 is suitable for limiting the freedom of movement of the breech of a handgun. Furthermore, the spear piece 32 is formed here by a bent piece of sheet metal that is supported and movably arranged on the inside 4a and the outside of the rear wall 4. The bent piece of sheet metal is then made, in particular, of tempered spring steel with great advantage. The locking piece, shown in perspective once again outside the cartridge magazine, has an approximately 90 degree angle Degree of angular deflection between two approximately 180 degree angular deflections. It also very preferably has a sheet thickness between 0.8 mm and 1.6 mm. In order to be able to absorb the forces of the breech, not shown here, of the handgun, also not shown, the locking piece is preferably also supported laterally on the edges of the free space 33. Even if the locking piece is only shown here for the sake of clarity Figure 3 the drawing of the preferred embodiment of the cartridge magazine is shown, it can and should of course be present in all of the figures shown.

Figure 4 gives an insight into the interior IR of the cartridge magazine 2, so that the inner surfaces 3a, 4a and 6a are clearly visible. The first projection 10 and the second projection 11 are shown hatched. It can be clearly seen here that the inner surface 3a of the front wall 3 has a first projection 10 which extends in the direction of the X-axis (cf. Figures 3 and 6th ) protrudes into the interior IR of the housing 1 and extends along the Z-axis starting from the intermediate area III at least partially into the first area I and at least also partially into the second area II, and that the inner surface 4a of the rear wall 4 has a second projection 11, which protrudes in the direction of the X-axis into the interior IR of the housing 1 and along the Z-axis a beginning 12 in the first area I, here even near the housing underside 7 and an end 13 in the intermediate area III or in the second Area II, the end 13 actually being in the intermediate area III here.

The beginning 19 and the end 20 of the additional projection 18 of the inner surface 6a of the second side wall 6 can also be seen in the left image area. Mirror-symmetrically to this, an additional projection 15 can also be provided on the inside 5a of the housing 1 (not shown here), as is also shown in FIG Figure 6 is recognizable.

The second feeder 27 is here pressed against the force of the second spring 29 into the space of the first feeder 26, which in the illustration is pressed deep into the interior of the area I against the force of a first spring 28. The first spring is between the first feeder 26 and the base plate 25 arranged, even if this is only indirectly so in the case shown, since an inner base plate 31 is also provided here between the first feeder 26 and base plate 25.

Figure 5 shows the cartridge magazine 2 according to the invention in a sectional view from a rear view in a, with cartridges P, partially loaded state. It can now be clearly seen that the first area I is designed to accommodate four rows of cartridges P arranged directly next to one another and preferably offset from one another in the Z direction, and that the second area II is designed to accommodate two rows of cartridges P directly next to one another and preferably in Z. -Direction offset from one another, arranged rows of cartridges P is formed.

The cartridges are arranged directly to one another because they are in direct contact, that is to say directly, at least in partial areas of their lateral surfaces.

By four next to each other (in Y-direction, compare Figures 3 and 6th ) arranged rows of cartridges, the parallel inner surfaces 5a and 6a of the first and second side walls 5 and 6 in area I occupy a distance B from one another, which in the example shown is about 1.95 times to 2, 05 times the distance C between the side inner surfaces arranged parallel to one another in area II.

In order to ensure a trouble-free and repeatable process sequence during operation during the step-by-step ascent of the cartridges P in the interior IR of the cartridge magazine 2, it is ensured that the cartridges P in the preferred exemplary embodiment are arranged directly adjacent to one another in all areas.

To support this, additional projections 15 and 18 are provided on the inner surfaces 5a and 6a of both side walls 5 and 6, which are formed in the intermediate area III along a first curved path 21 and a second curved path 22, the curved paths 21, 22 each having a turning point 23, 24 and move away from the underside of the housing 7 (compare for example Figure 1 ) to the top of the housing 8 (compare for example Figure 1 or Figure 4 ) in front of the respective turning point 23, 24 in the direction of the central plane M (cf. Figure 3 or 6th ) extend and behind the respective turning point 23, 24 cling to a first and a second parallel to the central plane M, which are formed here by the inner surfaces 5a and 6a of the first and second side walls 5 and 6 in area II.

In this case, the curved paths 21, 22 are designed mirror-symmetrically to the center plane M, but the first 21 and the second curved path 22 are arranged offset from one another by an offset V in the Z direction.

The selected offset V is between 7% and 35%, in particular between 10% and 25% and very particularly between 18% and 22% of the difference between distance B and distance C.

From the in Figure 6 shown cross section of the housing 1 of the cartridge magazine 2 can be seen that the housing 1 of the in the Figures 1 to 6 illustrated cartridge magazine 2 is integrally formed.

The housing 1 should consist of a homogeneous material, in particular the structure of the material over the entire housing 1 is essentially of the same design and consists here of a plastic. The plastic should preferably consist of a reinforced polyamide. Since the cartridge magazine is designed to hold a large number of cartridges and preferably provides between 50 and 80 cartridges, for example 60 cartridges for operating a handgun without having to change the magazine in the meantime, the cartridge magazine is also made from polyetheretherketone (PEEK) as the first cartridge magazine Provided.

The cross section shown also shows that the cross section of the first region I extending along the X axis and the Y axis is divided into a rectangular zone Z1 and a trapezoidal zone Z2 adjoining the rectangular zone Z1. The cross-section of the second region II, which is not explicitly shown again, is designed accordingly.
