I just got a PP 9x17, serial no. 70775a. Was hoping to find out a lil bit more info about this gun. I took it to pawn shop and they offered me $350, which is a nice return on $40 I payed for it. But got me thinking if a pawn shop offered me that much for it. That it’s got to be worth a lot more than that. Any additional info would be much appreciated.
