Extractor device of a firearm

A firearm comprising:

• a frame;
• a slide;
• a barrel;
• an extractor assembly (100) having:
• an extractor (110) mounted to the slide rotatably about an axis of rotation and having:
• a first and and a second end, the first end closer to the barrel than the second end;
• and
• an extractor claw (111) at the first end of the extractor (110);
• a guide element (112) protruding from the second end of the extractor (110);
• and
• an extractor spring (120) in a hole (113) of the extractor (110) biasing the extractor (110),
• wherein:
• the guide element (112) is biased in the direction of a control link (130) by the extractor spring (120), said control link being a surface of an extractor pocket (310) in a breech section (300) of the slide and forming a bearing of the extractor;
• first and second ends of the surface of the extractor pocket are concave;
• the guide element has a region (116) for sliding in the hole and a head section (115) of lower diameter than the region (116);
• the head section has a rounded end (114);
• and
• a shoulder is at a junction of the head and the region (116).

• an extractor assembly (100) having:
• an extractor (110) mounted to the slide rotatably about an axis of rotation and having:
• a first and and a second end, the first end closer to the barrel than the second end;
• and
• an extractor claw (111) at the first end;
• a guide element (112) protruding from the second end;
• an extractor spring (120) biasing the guide element from the extractor (110) to contact a surface of an extractor pocket (310) in a breech section (300) of the slide,
• wherein:
• the extractor pocket is shaped to allow an end (114) of the guide element to slide between a first end (1301) and a second end (1302) of a bearing section of the extractor pocket, the bearing section first end radially remote of the barrel relative to the bearing section second end;
• and
• the bearing section first and second ends are concave.

• and
• an axis of rotation of the extractor (110) and an attachment surface (1111) of the extractor claw (111) for contacting a circumferential groove (410) of a cartridge are at the same distance from the central axis of the barrel when the end (114) of the guide element contacts the first end (1301) of the bearing section.
