I have a all stainless steel, DAO, S&W 5946 which is a fine gun, though a bit heavy, around 38 ounces empty. The RCMP was one agency that used this model. RCMP also used the 3953, a stainless/alloy, DAO, single stack compact. I have one of those too. I like it better than the 3913 I used to own.
I also have a Beretta 92FS Inox. It is three or four ounces lighter than the 5946 but much larger and thicker. I do not really consider it a CCW, but it can be done.
I also have a two tone, DAO, Sig P228. Real slick and lighter than the other high capacity guns. I am also fond of the single stack P225 series.
I like them all. If I could only have one I would have to pick the Sig P228.
