[0189] FIG. 5 shows a possible profile design of housing section shell 3 and/or of housing shell 15.

[0190] FIG. 6a shows a cartridge magazine 2, 10 and a conversion kit with housing section 1 in a partially detached state, wherein FIG. 6b shows cartridge magazine 10 and the conversion kit with housing section 1 in a further assembled, however still partially detached, state.

[0191] Disclosed in the drawings and shown at least in respective individual figures is a housing section 1 for a cartridge magazine 2, and/or 10 for a portable firearm which is not shown here and which may be designed as a long weapon or as a short weapon, wherein housing section 1 is defined by a housing section shell 3, extending along an X-axis, a Y-axis and a Z-axis, wherein housing section shell 3 forms an inside shell surface 4 and an outside shell surface 5 and in its interior includes an interior space IR, limited by inside shell surface 4, and interior space IR forms at least a first region I and a second region II, wherein housing section 1 includes a housing section top side 6 and a housing section bottom side 7, wherein housing section top side 6 has a first opening cross section Q-1, and housing section bottom side 7 has a second opening cross section Q-2, wherein first region I is formed by a first cross-section Q1 for accommodating a first number N1 of rows R of cartridges P arranged next to one another and optionally offset from one another in the Z-direction, and that second region II is formed by a second cross-section Q2 for accommodating a second number N2 of rows R of cartridges P arranged side by side and optionally offset from each other in the Z-direction, and wherein second number N2 and first number N1 differ from one another by at least one full numerical value, and first cross section Q1 is consistent with first opening cross section Q-1.

[0192] In the illustrated example, housing section 1 is designed such that its first locking section is configured for a cartridge magazine 2 of a self-loading pistol, in particular for a model from the Glock pistol series, for example Model 17, Model 19 or another model. This series of pistols or family of models has a very wide distribution in the police market today. In the USA, about 40% of all police officers are equipped with a model from this model family. Cartridge magazines 2 of this family of models are designed in two rows, so that in this case the following applies for the housing section 1: first number N1 assumes a numerical value of 2. To achieve the highest possible magazine capacity gains and also to make the grip design as ergonomic as possible for the operator, for example a police officer, second number N2 has herein a numerical value of 4. In other words, the first region is then designed to accommodate two rows of cartridges, optionally arranged directly next to one another and optionally offset from one another in Z-direction, and the second region is designed to accommodate four rows of cartridges, optionally arranged directly next to one another and optionally offset from one another in Z-direction.

[0193] Another self-loading pistol model that is also very popular around the world is the Model 1911, which was originally introduced to the market by Colt and since then has been, and still is, produced in almost countless variations by a variety of different manufacturers. Model 1911 was originally designed for a single-row cartridge magazine, so that a housing section 1 aligned therewith is then designed in such a way that the first number assumes a numerical value of 1, wherein the second numerical value could then—depending on the design of housing section 1—assume a number of 2, of 3 or also of 4.

[0194] Self-loading pistols according to the prototype of a 1911 model, as well as self-loading pistols of the aforementioned Glock pistol series and also other comparable families of self-loading pistol and/or models, such as those of the companies, SIG, SIG-Sauer, Beretta, Heckler & Koch, Smith & Wesson, Walther, Ruger, Taurus, Browning and many others, are often equipped for one of the following calibers: 9 mm Luger, .357 SIG, .40 Smith & Wesson, 10 mm Auto or .45 ACP.

[0195] Such cartridges have a ratio of cartridge length to projectile caliber of less than 3.05, in some cases less than 2.65 and in some cases even less than 2.42, which is why, in deviation from a profile design shown in FIG. 6, the housing section jacket in the other figures is designed in this way that the extension of the first protrusion in X-direction is less than 4.5% of A, in particular less than 2.5% of A and quite particularly less than 1.5% of A, and/or the extension of the second protrusion in X-direction is less than 4.5% of A, in particular less than 2.5% of A and quite particularly less than 1.5% of A, wherein here the respective inside surface of the respective front and/or rear wall of the housing section and/or of the housing are formed in at least one region, optionally in all regions, free of a protrusion extending into the interior space in X-direction. The first cross-section and the second cross-section of the housing section set to one of the above ratios.

[0196] Moreover, it can be seen in the figures that a transitional region III is arranged between first region I and second region II, connecting first region I and second region II with each other.

[0197] It can therein be seen that first region I is designed to accommodate first number N1 of rows R of cartridges P in such a way that cartridges P of all rows R covered by first number N1 are to be arranged directly next to one another and optionally offset from one another in Z-direction.

[0198] Likewise, second region II is designed to accommodate second number N2 of rows R of cartridges P in such a way that cartridges P of all rows R covered by second number N2 are to be arranged directly next to one another and optionally offset from one another in Z-direction.

[0199] Intermediate region III is also designed to accommodate an intermediate number of rows R of cartridges P in such a way that cartridges P of all rows R covered by intermediate number NZ are to be arranged directly next to one another and optionally offset from one another in Z-direction.

[0200] Moreover, it can be seen in particular in FIGS. 1 and 2 that a first locking section 8 adjoins first opening cross section Q-1 in Z-direction on housing section top side 6 and/or surrounds first opening cross section Q-1 on the outside at least in X-direction and/or Y direction, wherein first locking section 8 is designed for releasable attachment to a housing 9 of a cartridge magazine 2, 10 for a portable firearm.

[0201] In addition, a locking section 11 is provided on the upper side of the housing section 6. Locking section 11 is provided for the releasable attachment of a locking element 12 shown in FIGS. 6.

[0202] It can also be seen, in particular when viewing FIGS. 1 and 2 and in conjunction with FIGS. 6a and 6b, that a second locking section 13 adjoins second opening cross-section Q-2 in Z-direction on housing section bottom side 7 and/or surrounds second opening cross-section Q-2 on the outside at least in X-direction and/or Y-direction, wherein second locking section 13 is configured for releasable attachment to a further housing section for a cartridge magazine 2, 10 for a portable firearm and/or to a base cover 14.

[0203] In the latter two FIGS. 6a and 6b, cartridge magazine 10 for a portable firearm is shown, wherein cartridge magazine 10 includes: one housing 9 for a cartridge magazine 2 and/or 10 for a portable firearm (not illustrated), defined by a housing shell 15 extending along an X-axis, a Y-axis and a Z-axis, wherein housing shell 15 has an inside housing shell surface 16 and an outside housing shell surface 17 and includes in its interior a housing interior space GIR, limited by the housing shell inside surface 16, wherein housing 9 includes a housing top side 18 and a housing bottom side 19, wherein magazine lips 19 are formed on housing top side 18, wherein the housing bottom side includes a base opening cross section Q-G, wherein a base locking section 21 adjoins the base opening cross-section Q-G in Z-direction on housing bottom side 19 and/or surrounds the base opening cross-section Q-G on the outside at least in X-direction and/or Y-direction, wherein base locking section 21 is suitable for releasable attachment of a housing section 1 for a cartridge magazine 2, 10 for a portable firearm and/or a base cover 14, 22, wherein cartridge magazine 2, 10 further includes at least one feeder 23, 24, at least one feeder spring 25, 26 and a bottom cover 22, wherein cartridge magazine 10 moreover includes a housing section 1, wherein housing section 1 is defined by a housing section shell 3, extending along an X-axis, a Y-axis, and a Z-axis, wherein housing section shell 3 has a shell inside surface 4 and a shell outside surface 5 and in its interior includes an interior space IR, limited by shell inside surface 4, and interior space IR forms at least a first region I and a second region II, wherein housing section 1 includes a housing section top side 6 and a housing section bottom side 7, wherein housing section top side 6 has a first opening cross section Q-1 and housing section bottom side 7 has a second opening cross section Q-2, wherein first region I is formed by a first cross-section Q1 for accommodating a first number N1 of rows R of cartridges P arranged next to one another and optionally offset from one another in Z-direction, and second region II is formed by a second cross-section Q2 for accommodating a second number N2 of rows R of cartridges P arranged side by side and optionally offset from each other in Z-direction, and wherein second number N2 and first number N1 differ from one another by at least one full numerical value and first cross section Q1 is consistent with first opening cross section Q-1, and wherein housing section 1 is arranged between housing 9 and bottom cover 14. Housing section 1 is herein optionally further developed according to what is described herein.

[0204] For example, it can be clearly seen from FIG. 4d that the at least one feeder 23, 24 is formed by a first feeder 23, wherein cartridge magazine 10 further includes a second feeder 24, and wherein first feeder 23 and second feeder 24 are designed so that first feeder 23 is at least partially movable into the space of second feeder 24, and optionally moreover, so that at least one feeder spring 25, 26 is represented by a first feeder spring 25 arranged between second feeder 24 and bottom cover 14, wherein cartridge magazine 10 further includes a second feeder spring 26 which is located between second feeder 24 and first feeder 23.

[0205] First feeder 23 is hereby arranged to be movable by a first degree of freedom F1 and a second degree of freedom F2 within the housing and/or the housing section and, in particular, within second feeder 24.

[0206] First feeder 23 is hereby arranged to pivot relative to the X-axis either from a first position L1 in which it is arranged at least partially inside second feeder 24 to a second position L2 in which it is arranged at least partially within second feeder 24, wherein the swivel angle is optionally between at least 4°, in particular at least 8°, especially between 12° and 21° to a maximum of 33°. Or, first feeder 23 is arranged to be pivotable relative to the X-axis from a first position L1 in which it is arranged at least partially inside second feeder 24 into a second position L2 in which it is arranged outside second feeder 24, wherein the pivot angle is optionally between at least 4°, in particular at least 8°, especially between 12° and 21° to a maximum of 33°.

[0207] The cartridge magazine moreover includes a locking element 12 which is illustrated in FIGS. 6a and 6b.

[0208] Locking element 12 has a first leg 27 having a first latch surface 28 and a second leg 29 having a second latch surface 30, wherein between first leg 27 and second leg 29 a connecting region 31 is provided which is connected to a blocking region 32 or forms a blocking region 32, wherein blocking region 32 has at least one contact surface 33 which is designed to accommodate a functional contact with housing 9.

[0209] Locking element 12 is designed optionally to be C-shaped.
