Not what I was looking for but more choice is a good thing.

I do wish S&W would decide on whether or not to include the weight of an empty magazine when they specify the weight of a gun on their website. According to the website the 3.6 inch gun is supposedly a couple of ounces heavier than the 4 inch model I have. I don't remember the specifics but when they came out with the first 2.0 guns it seems the published weight dropped by about the weight of a magazine.
