I currently have thre snubbies.
Colt Magnum Carry .357 2"
Colt SFV1 .38 2" (like a detective special)
S&W M60 Ladysmith .357 2"
The Magnum Carry is a six shot with a Hogue rubber boot grip from the factory. It is the largest of the three. It's comfortable to shoot .357, and is my wife's personal favorite for protection. The grip is soft rubber, which makes it a little tacky, so material tends to cling to it.
The SFV1 is a six shot .38 with hard rubber grips. The grips and cylinder are a shade smaller, making it more ideal for my wife's usual method of concealment. The grips do not cause material to cling like the Magnum Carry's. It is very comfortable to shoot .38's, even the hotter loads.
The M60 is the smallest of the three, by quite a bit. It's a five shot .357 with small wood grips. I can slip it in my front pocket with ease, and it disapears. It is the least comfortable to shoot, of the three. My wife does not like it at all. The small, smooth grips allow the gun to jump around in your hand with .38+P loads. When I shoot .357 through it using a two handed grip, it hurts the thumb of my support hand with every shot.
They're all great guns,but each has subtle advantages and disadvantages when comparing them.
If you want your Lady to like whatever you get, you should look at different models and let her get what she likes. If you want a home/field gun, a three inch or four inch barrel may be more practical.
A two inch tube is as acurate as a four inch tube from the bench, but it is hard to point shoot a two inch barrel with any acuracy, in my experience.
If I was in a threat situation it would take way too long to draw and line up the tiny front and rear sights on any of the above mentioned guns. I would point shoot. The results are acceptable at ten to fifteen feet, but beyond that, I would want to be taking careful aim.
The other posters all know a lot more about this than I do. I just thought my personal experience with these models may be of some assistance. Good luck with your decision.
