I got interested in it a while back myself - beginning of 2006, if I remember. I kinda liked the look, and did a lot of google searches on it. Also, did some searches on the Sig Forum. All reviews I have read were good. Most comments on the Sig Forum claimed that the trigger was nicer than most of the metal Sigs (people here have later agrued against that, but that was the sentiment at the Sig Forum).
Then I finally got a chance to hold one at a gun show... I didn't like the grip. I found it too blocky and bug. That turned me away from it.
