Thats the first I've seen of one called a "tribute", but as Judge has mentioned it's made by Walther.
I've owned one since they first were released in 2012. I have the Gold Cup Trophy version. I know some don't like the fact that they are made by someone other than Colt, but I can tell you that for the money they are a very enjoyable plinker that has decent accuracy and is well made. Mine goes to the range on every visit and it feeds anything.
