I will only add to that advice by saying the rubber grips are a fine choice for shooting, however I would not recommend leaving them on for storage...Over time they will leave a nasty mark in the metal which may be very difficult to remove...I have a friend who inherited the 4" nickel 29-2 which his Dad carried on duty as a California sheriff's deputy in the 60's...It still had the Pachmayr grips on it which his Dad favored for comfort...When he took them off to see how it looked with the original target stocks, the rubber had left its damage on the finish, and no amount of his or my efforts would remove it...And being oversize Pachmayrs, the black smears on the nickel finish were outside the area covered by the originals, and were even more visible...
So the advice to shoot with rubber grips is sound, but after returning from the range, remove them, clean the gun properly and put those beautiful Cokes back on for storage...You can thank us later for that advice...
