Magazine of a pistol for cartridges with a case rim, and pistol having such a magazine

A magazine for cartridges, said magazine comprising:

• a hollow magazine body having side walls extending in a longitudinal direction at an angle from a horizontal plane, an end wall, a rear wall, and a base plate having a bottom surface in said horizontal plane, said magazine body having a length and an upper end region forming a narrowing portion guiding together two vertically offset rows of cartridges to form a single row;
• a feeder guided in said magazine body having a bearing surface and an opposing bottom surface, said bearing surface being convex in said longitudinal direction and altering an angle of inclination of a cartridge located thereon in relation to the horizontal plane;
• compression springs between said feeder and said base plate and said compression springs seat within said opposing bottom surface, said compression springs applying force to said feeder in an upward direction towards said magazine upper end region, and extending predominantly the length of said magazine in said upward direction;
• said magazine body side walls including top inclined portions, inclined inwardly about a first angle forming magazine lips which enclose an uppermost cartridge centrally, said side walls including inwardly directed, first beads which run over a length of said side walls and merge in the upper region into converging guide ribs, wherein inner edges of said first beads run inward at a second angle, which is smaller than said first angle, and second beads located on a lower portion of said magazine body side walls serving to guide said circular compression springs and prevent lateral buckling thereof.
