By now, many of you Ruger Mark IV pistol owners, who sent in your grip frame for the recall fix, should have your pistol back.
It's never been made really clear exactly just what the fix entailed. Certainly the addition of an "S" emblazoned onto the safety plate would not be a fix of any major proportion, so what could be the issue?
I discovered very early on with the Ruger Mark IV pistols, that the "thumb safety detent" is black plastic, provided by the factory on newly shipped pistols. The on/off switching of the safety, if done regularly, will wear the radiused end of the plastic detent down quite quickly, so I replaced the plastic safety detent with a steel detent, same one as is used on the Ruger Mark I, II, III & 22/45 pistol thumb safeties. Mark IV safeties worked terrific after the change.
Here's what makes me curious that the plastic safety detent is the culprit. Ruger is "out-of-stock" on all the Ruger steel thumb safety detent, P/N KA02511. Brownells & Midway USA are also O.O.S. Even Numrich Arms is O.O.S, not only on the Ruger Mark steel safety detent, but even those for the AMT Lightning, which has a safety very similar to what the Ruger safety is.
So, if/when, you get your pistol back from the Ruger recall, could you check to see if the visible end of the safety detent is either black, or silver? I would hope that Ruger is doing the right thing and replacing the detent with the steel version that has been working just fine for 68 years.
