I am not familiar with the Morini grips, but I do know that Herrett makes a nice set of wood grips for the Ruger Mark II. They are called "Nationals" and come with either a left or right thumb rest and also have an adjustable heal rest. I have a set on one of my Mark II pistols and love them. I don't carry them in stock but they can be ordered from Gil Hebard Guns in Illinois. Their phone number is (309)289-2700.
