Lucky fellow.
If S&W were to ask me what I'd want made, I'd ask for an all-stainless steel 3916 without a rail (not a real model number, but what I'd think it would be if made), and/or a 3913TSW Sc without a rail (or at least an integral machined rail) with a black finish Scandium aluminum frame and a Melonite treated slide ... both with the spring-loaded, decock-only option (which I have on my late-production 3913 and really find practical and useful for my needs).
Not gonna happen, but that's what I'd want made ...
I'm not a DAO-type guy when it comes to S&W 3rd gen guns, myself. I just prefer TDA.
Nice to dream, though.
As much as I like my CS9, G26 & SW99 9c, and felt the M&P 9c I handled and tried at the range was a very nicely balanced and ergonomic gun (and which was much easier to shoot rapidly & accurately than my M&P 40c) ... I still find the 3913 (and it's variations) to be an excellent model line when it comes to a compact defensive 9mm pistol.
I think S&W missed the boat by not making the 3906 in a reduced size (or an all-steel 6906, which I always thought should rightly have been called a 6913, with an all-stainless steel model being called a 6916). Talk about a couple of compact 9mm's that would absorb felt recoil and enhance controllability at the expense of only a little more weight ...
