Armi San Paolo was an Italian manufacturer founded in 1970by the infamous Grassi, Doninelli, and Gazzola.  By 2002 they were integrated into a new maker named Euroarms Italia SRL. The logo found on some ASP revolvers is the same as that of the Euroarms logo, which represents the first three letters of the name of the founders of Armi San Paolo, Grassi, Doninelli, and Gazzola.    The three letters are usually contained in a circle, but can also be found without the circle around the letters. DGG Early on, EMF imported DGG made revolvers.  Euroarms ceased manufacturing in 2011.  (See the DGG photos and the Euroarms photos for more information).
