I stumbled upon this thread in my ongoing attempt to see if Smith has released more 2.0 C.O.R.E. pistols. I am eager to get a 4" model. My rep said they are coming but at SHOT show this year everyone in the Smith booth acted like they had no idea. I did get the standard model last year and really like it. Everyone I show it to wants one.
