I have a Ruger GP100 10-shot 22 LR. I have not shot it yet but picked it over the S&W 617. I like a semi-lug barrel and the 5.5 inch barrel is more to my liking than either a 4 inch or 6 inch full lug barrel. And three points of cylinder and cycling support versus only two points for the 617.
Will report if it shoots well later. The late Jeff Quinn of Gun Tests reviewed this Ruger and his assessment sold me on it.
