The body is pivotally mounted via a pivot pin. A surface is positioned between the pivot pin and the hook. The surface is divided into at least two surface portions offset from one another. One of the surface portions has a plurality of step surfaces offset from one another. The step surfaces are used to fix the bar dimension of the hook. The invention also encompasses a slide on which the extractor is mounted, as well as a self-loading firearm having the slide. A method of fitting the extractor to the pistol or slide is also disclosed. ## Claims ### Claim 1 An extractor mountable on a breech block of a self-loading firearm by means of a pivot pin, said extractor comprising: a body attachable to said breech block and having a hook positioned at one end thereof;
