Just got these recently, I already have a 6" blue King Cobra and went to an auction and got these for about $400 each. The Trooper III was a local Deputy Sheriff's duty gun, and the DS was his off duty piece.
The Trooper shoots like a dream and it looks how I like my guns, lots of character but not abused. IMO Colts look better with some holster wear and a few dings in the grips
I admit I'm a Ruger DA revolver fanatic but I love the Colt Mark III series. I want a Lawman Mark III and an Official Police Mark III next.
