This forum that we are in now is a sub-forum of the general S&W semi-auto pistol forum. The general S&W semi-auto pistols forum is where there seems to be all the info about third-gens.
You can get there by clicking on the "Smith & Wesson Semi-auto Pistols" root thingy above just below the website's logo, or go to
Smith & Wesson Semi-auto Pistols and look just a little lower on the page and you'll see the general discussion area for S&W autos.
The way the page presents itself on my browser, all you see is the subforum links unless you physically scroll down. If you don't scroll down, you can miss it.
