I like those GP-100's so much I bought five and sold four.
Bought a 4" .357, it was great. Trigger not as good as my S&W 586 but just as accurate. After a couple of years got a wild hair for something shiny and sold it. Then about 6 months later thought "that was dumb" and bought another. Then a couple of years later sold that for some other infatuation. Then a year later thought "geez, I really liked that GP100, why did I sell it?" and bought another.
Did that over and over until I got a 6" stainless half lug. Have managed not to do anything stupid with that (i.e. sell it) for a several years now.
