Abstract
An extractor for the removal of cartridge cases from the chambers of a revolver is mounted adjacent the outer end of a tubular stem. The extractor is in the form of a plate having a plurality of radially extending arms equally spaced apart and defining, between each adjacent pair of the arms, a cylindrical surface which conforms with the inner cylindrical surface portion of one cartridge chamber of the revolver cylinder. The outer edge portion of each of the arms is generally a rectilinear edge and together define a rectangular shape having its geometric center aligned with the longitudinal axis of the stem. The revolver cylinder includes a recess in the rear surface of the cylinder which has a depth approximately equal to the thickness of the extractor plate and includes inner, rectilinear edge portions contiguous to and parallel with each of the outer edge portions of the extractor arms to limit rotation of the extractor plate relative to the axis of the cylinder.
