Recently went from thinking of purchasing to purchasing a police trade-in Smith & Wesson 5906. New to the platform but it seems to be in great condition. Initial range visit went well. Operates as advertised. From a supported rest it is pretty accurate to seven yards. Free hand, not so much. I have to acclimate myself to the SA trigger I guess. :)
And it seems to be a nice trigger. In SA the word "crisp" comes to mind. Reset is fantastically short. Never been a fan of DA triggers but this one is smooth.
I used this excellent four video tutorial series on YouTube to disassemble the pistol:

SIDE NOTE: this is by far some of the best produced DIY gun videos I've seen on YouTube. They are well lit (that alone gets my vote), clear, well mic'd (he seems to have used an external mic instead of the on-camera mic), and informative. If you have a third gen S&W semi you owe it to yourself to give these and the gunsmithing videos (stay tuned for that) a viewing.
I will be using the aforementioned gunsmithing video series (http://youtu.be/W6qUBHIdWX4) to polish some of the components. I'm not a smith and you all will see this warts and all. Everyone is welcome to offer up any advice. I'm good that way.
I'll update as I go along.
Here is what I'm starting with:
