I've had a 6" blue half-lug .357 since 1989; it was my tree stand "deer rifle" for many years. Now it's a range queen. Just got a stainless 3" fixed sight .357 for carry in the boonies and put Altamont grips on it, which I much prefer to any of the factory Ruger grips, including the old compacts. They are just long enough so all of all of my fingers fit naturally, without any "pinkie hangover"!
GPs are the best overall .357 revolver I've shot, and that includes Smith K, L, and N frames and Colt Pythons. You made a great choice. If it seems too muzzle-heavy for you, send it to Ahlmans in Minnesota and have them make it into a "half-lug." Those few ounces off the front of the barrel make a great difference in the handling and balance for some folks.
