Hallo, I'm looking to buy a Tanfoglio Stock 3 Xtreme. And would like to know if it's needed to be done a trigger job. (I imagine, but not sure, to polish the sear and hammer at least) I've read about the Stock 3 and the Stock 3 special, and seems that the trigger comes from factory heavy and they need a trigger job (for less weight and let it smooth). I wonder if the Xtreme needs it or not. One of the sellers says yes, the other one says no, and also says that if I want less weight its a matter of springs. As you can imagine the Xtreme from the seller that says yes, its more expensive. Thank you in advance.
