I sent my Mk IV back to Ruger for their recall due to problems with the safety. They sent me a mailing box and I had it in the mail in a jiff. Turn around time was 12 days door to door. The new safety is a big white dot with an "S" in the middle.
Forgot to mention that they also sent me a new magazine for my trouble.
