Ruger American pro.45 acp issues

[Grimdarr]

I am having issues with the Ruger American pro.45 acp the slide is getting loose from the receiver any idea how to tighten it back up... Under the barrel and receiver is really loose almost spongy some real play in it I had sent it to Ruger for failure to lock slide it came back working great went and shot it once and now it is back to being spongy again I own a Ruger American pro 9mm no issues at all so I used it for how tight it should be and my 45 is bad really bad help please

I would call ruger and let them fix it. They are really good and usually a quick turn around.
