I think the alert for all shields prior to 8/19 is a CYA thing by S&W. If this was a wide spread problem it would of been brought up by someone a long time ago on this forum alone.

Mine with a build date of 6/24 checks out fine!

Let us know if anyone here finds that they have an issue. If I was a betting man I'd estimate the odds are <1% of us have an issue.
