Today at the range I rented a 617 4" 10 shot. I shot good with it. While shooting it, I realized that most of the "feel" on a double action trigger is the cocking of the hammer, and the spring. The rotation of the cylinder does not play into it that much. In my mind, I thought it would be more significant. I did not like the full lug barrel. Unneeded weight if I wanted to pack it small game hunting.
