Hi all. I'm new to 1911s and am planning to purchase my first Colt soon. I want a Series 70, blued model 01970A1CS. Gun Broker has them anywhere from $999-$1250 for a stock pistol NIB but more often than not, GB is way overpriced. Online, I found a guy near me locally with one, NIB, that even has the "100 Year of Service" rollmark on the slide. He said, "make me an offer". Anybody have some intel on what a fair price on this pistol should be? Thanks.
