I have a chance to buy one that was actually a department gun for a local small town PD from the officer who carried it(No I do not live in Mayberry...lol). Have not seen it yet, but assuming it's in very good/great shape is $575 a decent deal? It includes everything as new except one of the mags. More importantly, Colt is releasing a new Mustang. How do you think this will, if at all, effect the value of the original Mustangs?
