If anyone has some insight on this gun I would appreciate it.
Well, few were made and I don't see these very often. I got the name confused with the "border patrol" model which was apparently a 38 special version of the MKIII trooper. The peacekeeper was a lesser finished version of a MKV trooper. IIRC it was Colt's employees who did finishing on the guns who went on strike, resulting in some lesser finished guns, such as this model. Many 1980s colt revolvers are valuable and sought after today compared to say 1970s examples for these reasons. All of the 80s Colt issues resulted in fewer revolvers made, which in turn results in higher values for many of them. An interesting piece and history, IMO.
