I've got a stainless steel DA S&W .357 mag. with a two inch barrel and fully adjustable rear sights and I can't find the modle anywhere on the gun. I believe the J frame is the smaller gun, is it not? If so, this is not a J frame, I had one of those MANY years ago (I think!). This is a six shooter, BTW. HOLD IT!! Its a modle 66-2. Why that can't be put in plain sight, I don't know. We old farts need a break! Anyway, is this gun a keeper or is there anything I should know that S&W is not spreading around?
