If it's a German SR9 and you can buy it for $1,500 (and it's not a scam, which it smells like) I would buy it NOW and get better pictures and ask your questions later.
Yup. I've been told that at that time the Williams set trigger was a $200 option.Trigger group is a Williams set trigger. Buy it
Agreed group looks like a Williams. Even if it wasn't the rifle itself is worth more than what you are buying it for. Grip looks to be one from Ergo.Trigger group is a Williams set trigger. Buy it
