I had the good fortune to run across a fine specimen(LNIB) of the 6906 from a forum member some days ago and although I haven't had the opportunity to shoot it yet(leaves took precedence) I'm sure it will shoot as good as it looks.
I thought it would probably be about the size of my 457 but, it's even smaller and although it's a double stack grip, it still doesn't feel big at all. I think I'm going to like it! Another fine example of S&W 3rd Gen technology.
