ABSTRACT:
A hand gun has a cylinder, a chamber in the cylinder for holding a shell casing, an extractor rod extending through the cylinder adjacent the chamber, an extractor on an end of the extractor rod normally held in a closed position adjacent the chamber, and a return spring around the extractor rod for normally biasing the extractor into its closed position. The extractor normally can slide the casing entirely out of the chamber in response to travel of the extractor rod. A safety bushing is secured around a portion of the extractor rod, and the return spring is biased against the safety bushing. The safety bushing reduces the travel of the extractor rod which, in turn, limits the distance that the extractor can move the shell casing out of the chamber. The length of the safety bushing is sufficient to prevent the extractor from sliding the casing entirely out of the chamber, but sufficient to still allow the casing to be easily removed from the chamber, so that a casing cannot be jammed in the chamber by the extractor under the bias of the return spring after the extractor rod has been actuated.
