Ruger will indeed take care of your revolver and send it back to 100% factory spec. Short stroking their design has been known to create issues though it really is kind of rare.
On another note anybody who sends a gun to Ruger should know that if they have a piece that they have spent good money to have slicked up or accurized by a smith when Ruger returns it it will be restored to factory specs. This means they will remove any parts that are re-worked or swapped out and replace with off the shelve parts. No more custom gun. S&W years ago would not do this however in this day and age I doubt they will let a gun out that has been altered but I don't know this for sure
