I have an opportunity to aquire a 1978 (the owner volunteered this) blued 6" DB for about $950 here in California. I noted it had rubber grips and a blue two latch plastic box that looks like it was made for it. From the photos I've seen the finish looks good and the owner said he was the second owner and he said it hadn't been shot much. I'm a complete newbie when it comes to Colts. Is this a fair price that's being asked?
