Colt Diamond Backs are unreal in price, when you can buy a python for a few dollars more. Diamond Backs are not worth the price I have seen any of them for.
Detective Specials are not an investment gun to buy. The market is litterly flooded with them. Buy one because you want one, not for the investment value.
You can still buy them NIB. They're from $425-$600.
