Ruger uses investment cast steel for the slide. SO? Glock fanboys are convinced they have the "best" pistol ever invented. In my experience, the Rugers are more accurate than the typical Glock. I'm a S&W guy, but would have no reservations about the Rugers. They just don't happen to be my favorites.
In life, strive to take the high road....It offers a better field of fire.
