Smith & Wesson has identified a condition that may exist in certain PPK and PPK/S pistols which may permit a round to be discharged without the trigger being pulled. When the manual safety is disengaged, Smith & Wesson’s Product Engineering Group has determined that the possibility exists in certain firearms that lowering the hammer may cause a chambered round to fire.
