Pro series
SGC, I can't speak for the 60 Pro but I did buy a 686+ Pro and it has a better trigger than the regular 686s and 686+s. In my case, it also had a 5" slab barrel which is unique in that most 686s have 4" and 6" barrels. BTW, my gun came with Hogue rubber grips which I didn't like and I replaced them with Rosewood grips. Bottom line, it's my understanding that all Pro series guns have special attention including trigger work given to them to make them a better shooter and unique with other attributes. Hope that helps. Regards, Elliot45
