I have a chance to buy a Champion from my brother in law. He bought it new last year, and only has 80 rounds through it. I know this for sure because I keep it in my safe. It has all the paper work, box everything that came with it. It's the OD green frame night sights and ambidextrous safety. He doesn't know what to sell it for, and I don't know how much to offer him. He did mention $ 600.00 a while back, but not sure if that offer still stands. The pistol is absolutely pristine condition. What do you guys think it's worth? Also it doesn't say on the slide "Champion Operator" just "Champion" but from what I see on the Springfield it appears to be the loaded model. What is the difference between the Champion and the Champion Operator?
