Colt’s six shot, .38-caliber blue steel revolver of medium size or D-frame. It is the original double action, short barrel revolver that popularized the snub genre. The Detective Special saw several changes or “series.” The First Series had a distinct exposed ejector rod and square butt. The Second Series retained the exposed ejector rod but introduced a rounded butt. The Third Series introduced an ejector rod shroud and changes in the internal lockwork. There was a final effort at producing the Detective Special called the Magnum Carry series which ran only briefly during the 1990’s
