  • the invention also relates to a method for operating a handgun using a cartridge magazine.
  • Cartridge magazines for handguns have been known for a long time and are manufactured in different designs according to the prior art.
  • the person skilled in the art first differentiates 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.
  • Permanently installed magazines generally offer the advantage that they cannot be lost and the disadvantage that reloading is quite time-consuming.
  • the cartridges must be inserted individually via the magazine lips of the permanently installed magazine, regardless of whether the permanently installed magazine is designed in the form of a box, in which the cartridges to be received are mounted in such a way that the cartridge lateral surfaces touch, or whether it is in the form of a tubular magazine is configured in which the cartridges to be accommodated touch one another on their front and rear end faces.
  • fast charging systems such as charging strips or charging tubes, are known for both variants, they are only moderately practical to use and have therefore not been relevant to official use for many decades.
  • In-line magazines are in turn fundamentally divided into linear in-line magazines, which are also called bar magazines, and arc-shaped in-line magazines.
  • the cartridges are stored in such a way that, when the cartridge magazine is at least partially filled, they touch tangentially on their case walls within the housing of the cartridge magazine.
  • the contact points or the contact lines of the cartridges shift tangentially and/or axially with each other, whereby the type and degree of Shift strongly from - can be dependent on the fill level of the cartridge magazine - which may also change at high frequency in discrete steps during operation.
  • drum magazines are therefore only used very little overall, both in the civilian and in the official sector, and there mostly only in military use, for example when operating firearms that are at least temporarily mounted on vehicles, where they form the link to belt-operated firearms, which are then In general, however, they can no longer be counted among the "handguns" that can be operated by hand.
  • Handguns are long and short guns that can be carried and operated manually. For operation with a cartridge magazine, repeating pistols and self-loading pistols are known in handguns. In a market analysis today, self-loading pistols play a role almost exclusively. Both repeating rifles and self-loading rifles that are designed for operation with cartridge magazines are also known in the case of long guns.
  • Cartridge magazines are model specific.
  • a handgun that has been in use by authorities around the world for several decades is a self-loading rifle based on the AR-15 / A 16 model.
  • this weapon has a magazine shaft that is open at the bottom and into which suitable cartridge magazines can be inserted.
  • cartridge magazines with different capacities are known. Magazines with a capacity of 20 or 30 cartridges are common today to operate this weapon model or similar handguns.
  • a handgun of the same type is understood to mean a self-loading rifle that 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 fired by pulling the trigger once and a second mode in which the Weapon can be operated in such a way that a plurality of shots is always triggered by the single actuation of its trigger.
  • the generic equality of the handgun described should also be maintained if the operator, when selecting a plurality of shots to be fired, also chooses between firing a closed group of shots, for example 3 or 5 shots bursts or one can choose continuous fire.
  • the cadence How quickly the shots are fired one after the other by the handgun when an automatic firing sequence is selected after only one pull of the trigger is referred to as the cadence.
  • the rate of fire of a handgun of the type described is generally between 600 rounds per minute and approximately 1200 rounds per minute.
  • Handguns in this context especially the self-loading pistols that can be operated with cartridge magazines, are carried concealed in contrast to long guns. Accordingly, there is a particularly high interest in compact dimensions of the self-loading pistol. Since most self-loading pistols are designed in such a way that they are designed to accommodate the cartridge magazine in the grip area, the maximum capacity of the respective cartridge magazine is then usually determined by the length of the grip area and often also by this limited.
  • cartridge magazines for handguns Since the capacity of cartridge magazines for handguns is on average significantly smaller than that of cartridge magazines for long guns and the cartridge magazines here can often only hold between 7 and 15 cartridges, it is common for a user, for example a police officer, to have one or two additional cartridge magazines carries with it. As a rule, these cartridge magazines should also be inconspicuous, i.e. covered, wearable on the body, but at least easy to handle.
  • model-specific cartridge magazines that are available in addition to a respective self-loading pistol are also referred to as interchangeable magazines in specialist circles.
  • Such interchangeable magazines are sometimes made a little longer, for example to hold one or two more cartridges.
  • cartridge magazines have been manufactured for the past 60 to 80 years, mostly using an extension unit that is often referred to as a "magazine shoe”.
  • Such magazine shoes are known from the prior art in a variety of ways. Versions have also become known which are designed to be optionally interchangeable with the base plate of a normal version of the respective cartridge magazine. From more recent times, here is an example U.S. 2017/0321979 A1 According to the generic term, this offers the user the advantage of redesigning the cartridge magazine according to different purposes, because handguns in particular are often used for different purposes.
  • a sports weapon can also be used for self-defense and is also used for hunting in some regions of the world, for example in North America. With regard to the requirement for concealed portability, temporarily different climatic conditions can even have an influence.
  • a cartridge magazine has become known whose housing is designed to be telescopically extendable and in this way the operator can choose between a first housing length with a first capacity and a second housing length with a second capacity.
  • an object of the invention can be seen as providing the user with a possibility of adjusting the capacity of a cartridge magazine for a handgun that is particularly favorable in terms of the ratio of the additional space required and the additional capacity gained, with this being particularly is to be evaluated in relation to a model-specific standard magazine design.

  • first number of rows of cartridges and the second number of rows of cartridges are each arranged directly next to one another and are preferably offset from one another in the Z direction has the advantage that the first number of rows and the second number cartridge stack sections formed by rows can each stabilize one another in a very good manner and thus form an excellent basis for safe and reliable operation of the cartridge magazine.

This offers an excellent compromise between the aforementioned advantages, even if a combination of two odd numerical values of the rows within a cartridge magazine applies and therefore seems surprising for the design of the proposed housing section. In yet other cases, it may be preferable for the first number to have a numerical value of 1 and the second number to have a numerical value of 4. Based on a single row, according to the applicant's previous findings, this probably offers the greatest possible increase in capacity, which appears to be functionally reliable
