Bought a Baretta 92D a bunch of years ago to use on my boat. The boat is history and the gun has become a safe dweller. I was wondering if, with all the expertise that haunts this web site, if anyone knows if it can be converted from a DAO to a DA/SA weapon? The gun is chambered in 9mm and has high capacity magazines. And...if the answer is affirmative, does it make economic sense to do so? It has less than 50 rounds thru the pipe.
