Several folks posted Lady Smiths and some random other small frame guns in another thread. Hopefully they will post up here.
Since you are asking for one, I assume you do not currently own one. With that, have you shot before? If not.... smaller guns GENERALLY have more recoil / kick, and take be a bit of a handful.
A 38 Special Revolver w/ a 4" Barrel would be a VERY good choice (if it fits your hand well) for what you are asking. My wife keeps our Ruger GP100 3" 357 Magnum (loaded w/ 38 Special) on her side.

Also, if you are not familiar, I would look into taking a firearm safety course. The might be able to steer you into a direction as well.
