I handled A Security Six at a pawn shop the other day. It had a 2 3/4 inch barrel was blued and original wood checkered grips. It had some very light rust which could likely be cleaned up. It was also missing the rear sight blade which I could order and replace. It still locks up well and felt pretty good. The asking price was $265 which seemed too high. What would be a fair counter offer for me to make?
