Congrats on your new purchase. Both the no-dash and the dash 1s were subject to the recall. The update was built into the dash 2s. You can check the FAQs if you'd like, there is a copy of the recall notice put out by S&W. And there have been a number of threads on the subject. I have several no-dash L frames that have never been modified and never had any trouble with them. All are great shooters.
