Hi to all. This is Don from Wisconsin. First time posting on this site. I recently purchased a Beretta 682 Gold E Sporting on Gunbroker. I broke it down and cleaned it and I noticed it has mechanical triggers. I have 2 other 682's....and both of them have inertia triggers. Did Beretta ever build these from the factory with mechanical triggers? Just trying to figure out if this could be factory installed......or installed by the previous owner.
