I too want to get a GP100 and am having a difficult time deciding on which one to get. I'm torn between the stainless full shroud 3" and the stainless full shroud 4" with adjustable sights. At this point my primary purpose would be for recreational shooting. I currently own the following .357's: a nickel S&W 4" 586, S&W 2 1/2" 66 and a S&W 640 Centennial. I am open to opinions as to which to get and would like to hear what others who have owned either one or both have to say. Thanks, Mike
