Dumante, I have sold several German made 226's in the EE for $1000 and they were all hardly used, some had no slide marks on the rails, like brand new. If you are after a German Gun, then buy a German Gun, they are superior to the U.S. made Guns and far far superior to CPO's. As for me I wouldn't take a free CPO if you gave it to me. They are truly junk and a good way for sig to sell off xs for big profit.
Be patient what you are looking for will show up. Or you can buy an HK that will be proofed with German proof marks and will be as good as the sig.
