I think you have type "D" double action only as opposed to type "C" constant action only. I've heard the "C" is pretty sweet. Your missing a couple parts however and your going to need at least the sear and trigger bar assembly for starters in order to make it a type "C". Maybe the trigger assembly as well. I don't know if you'll be able to covert to a type FS DA/SA however. Go to Brownells and look at the schematic and you'll see what the "D" action is missing to make it a "C" or perhaps "G" or "FS". I'm not a gunsmith, but it looks like it's possible. I'd call Beretta and ask them if it's possible as well. Your surely doing it the hard way, but the parts are very inexpensive.
