RE: What is a Lady Smith
LadySmith was a marketing move, not a model. S&W sold several "feminized" handguns under the LadySmith name for a few years (late 80's, early 90's, maybe?). They were characterized (as I recall) by having features like satin finishes and rosewood grips, that sort of thing.
A nice idea, but I don't think it really took well.
