A guy at work approached me to buy his Colt 1991 for $850. I don't know much about colts so I was wondering what you think? Hopefully Canebrake will chime in he also told me it was a model 70 and that he thought it should be worth around $1100? He is sending me pictures of the gun tonight and ill post them to give you a better ideal of the model and the condition. Thanks in advance.
