I bought this P320 Carry new from a gun store several years ago. When I bought it was when they first came out and at first two employees said they didn’t have any in stock. After talking to someone else they said they had one I could buy. Don’t know why but I got curious so I called Sig today was told it was manufactured in the fist run of the P320 before they changed them. Can anyone tell me what was changed? Kept asking the guy at Sig but kind of got a run around. All he would say you have a great pistol. I know I have a great pistol.
