Abstract
An extractor for the removal of cartridges from the cylinder bores of a revolver. The extractor includes an extractor plate having a plurality of arms extending radially outward from an inner portion of the plate. The arms form an inner surface between adjacent arms. The inner surface substantially conforms to the profile of a bore of the cylinder and has an arc length that is greater than one-half the circumference of a cartridge disposed within the cylinder bores of the revolver. The inner surface contacts the rim of a cartridge and facilitates the removal of the cartridge from the bore. The inner surface may also include a beveled edge and the arms may have convex or concave end portions. The extractor also includes a tubular stem mounted to the inner portion of the extractor plate.
