kidcolt, welcome to Coltforum.
We typically need photos to opine on value of a firearm. Besides, we like to look at photos of Colt firearms. Seeing photos motivates us to offer our opinions. If you put out the effort to post photos, we put out the effort to tell you what you are looking at, and answer your questions.
That said, IMHO, you ought to try to negotiate down the price by one or two hundred dollars, then go ahead and buy the Colt at whatever the resultant price turns out to be. I do not see how you could get hurt, buying that gun (assuming REALLY new) for $1300. Be aware that representing a gun that has some wear on it as a new gun is a common misrepresentation.
