 The quality of Type 94 Nambu pistols decreased towards the end of World War II as the Japanese faced bombing raids from allied forces and material shortages increased . This drastic change in quality from late March 1945 , onwards with all quality standards appearing to disappear towards the end of June 1945 . The smooth wooden finished grip was replaced by a <unk> <unk> pattern . Many pistols were not serialized and no pistols have been reported that bear July 1945 manufacture date . Only four <unk> and undated pistols are known to exist and include <unk> parts with no inspection marks , <unk> loops , and <unk> . A small number of pistols made during the final production stages include earlier production dates and appear to have been salvaged from previously discarded pistols that had minor or cosmetic defects .
