The recall notice is for Shields made before 8/19, so I will definitely check that.Double check it is post recall when you get it, and verify the drop safety anyway.
I got one off of GB that was supposed to be post recall but was really built in April. I let the seller know it was misleading, but because I ended up paying less than a LGS and it did not have the safety issue, it is fine.
I did call Smith and Wesson and their story is the guns with problem shipped that way....they will not develop it over time.
