A guy who works for me has a friend that is selling off his dad's firearms collection and has one pistol that caught my eye. Its a used Sig P226 9mm blued. Looks to be in pretty good shape. He told me to "make him an offer". I have no idea what a fair price on a used P226 would be. Any idea what a "fair" price would be on this handgun? I want to get a good deal but I don't want to insult him either (if that makes sense). Thanks.
