I'm guessing it was providence when I was sitting at the gun shop and a guy wanted to trade in a pre-lock NIB 442 for one with a lock "because of his wife"

When the dealer gave him a price, I told the guy, lets step outside a moment....

all things considered, it was the extra parts thing that always bugged me, but that's because murphy is my constant companion.

No magazine disconnect or safety on my M&P either...
