An extractor of a firearm is mounted rotatably about a rotation point with an extractor claw in the region of an end of the extractor near the barrel of the firearm and a contact element in the region of an end of the extractor remote from the barrel. An extractor spring biases the extractor in an end position determined when the chamber is empty. Torque-free pulling of a cartridge case is made possible in that the extractor has a protrusion mounted in a pot of the breech. The protrusion's leading edge adjoins an undersurface of the protrusion. The protrusion is mounted on a bottom surface of the pot near the barrel. The protrusion leading edge is supported on a leading edge of the pot near the barrel. The pot leading edge forms the transition from the bottom surface to a boundary wall of the pot near the barrel. The leading edge forms a rotation axis of the extractor, which allows rotation of the extractor relative to the breech.
An extractor device (100) mounted in a breech (200) with a lower part with functional elements for interaction with an upper region of a handle part (300) of a firearm with an extractor (110) which is rotatably mounted around a pivot point with an extractor claw (111) provided in the region of an end of the extractor (110) near the barrel (250) of the firearm and a contact element (112) arranged in the region of an end of the extractor (110) remote from the barrel (250) of the firearm, with an extractor spring (120) biasing the extractor (110), characterized in that the extractor (110) has a protrusion (140) mounted in a pot (210) of the breech (200), the leading edge (1411) of which near the barrel resting on a bottom surface (213) of the pot (210) and adjoining an undersurface (143) of the protrusion (140) is supported on a leading edge (2133) of the pot (210) forming the transition from the bottom surface (213) of the pot (210) to a boundary wall (211) of the pot (210) near the barrel and forms an axis of rotation (1411) of the extractor (110), which allows rotation of the extractor (110) relative to the breech (200).
