As far as I know it's not out yet.
The list of goody's on it is very impressive.
Supposedly a limited number will become available this summer.
This thing was supposed to be out last year. I can't figure out why the delay in getting a 100 year old design out is happening.
I too am waiting with bated breath for the new Taurus 1911SS. But, my local gunshop owner says it's still not available.
I have the Taurus PT-145 Millenium, (pre Pro) and I love it. I bought it used and did have a problem with it. I sent it in, and it was returned in two weeks with a new trigger/spring, slide adjustments and new slide release. No charge! It has been 100% reliable ever since. The PT-145 rides with me every day. I am thinking about getting the millenium Pro with the SS slide and picatinny rail.
