Why I have no idea, it's not like I needed another 3rd gen 9mm. But it was a good deal and I was casually looking for another DAO with Trijicons. I'll shoot it with the straight grips before deciding whether to switch to the curved ones I'm familiar with.
After a couple years of searching I just made my own with a 5943 frame and a 6946 barrel/slide. After seeing your pic I am going to send the slide in for some kind of black coating. Gotta love the S&W two tones.
