Hello, Good Luck trying to find one of the DSS M-19's ! I've noted a few varying totals on them, but I haven't observed any firm, conclusive data as to exactly how many were mfg'd. My example is the 4" type, polished blue finish, & all correct w/ original box. According to an E-Mail from S&W, it was 1 of 680 or so pieces mfg'd for the U.S. Dept. of State in March of 1988. You should initiate a search here in the both the Forum & the Web, in which you should come up with numerous threads. Good Luck,

Best, dpast32
