Are they doing this because people thought it would be a good idea, or because they did some testing and found that it solved some problems?
Many months ago, a gunsmith I trust, Bruce Gray, suggested that issues with the R9 might be "magazine timing" issues. More recently, others have suggested the same thing. We have also seen suggestions that new floor plates, which hold the magazine in the grip a bit more tightly, might help. So the stronger magazine spring idea was born.
Finally, why wait until January 2007 before shipping these standard? If they solve problems, why not phase them in right away? I have a stealth on order and will probably get it before January, so now I am thinking I should hold off, since I won't want to pay extra for magazine springs I need. If they don't solve problems, well, then why would Rohrbaugh be doing it?
