It's not a DAO S&W 3rd Gen, but my California Highway Patrol 4006TSW does have a bobbed hammer and a decocker only safety.
But then again, if I could only own one, then this would be it. I wanted one of these since they first hit the civilian market in 2017, but only just managed to get my hands on one earlier this year when another wave of them way released. In many ways, it was my "grail gun" as they call it, so I'm satisfied with it.
