At the very least, get a S&W .380 Bodyguard. It has a integrated laser in it. It may be a sacrifice as far as real stopping power goes but it is better than nothing at all. Plus with the right ammo, it can be a nasty little mother.
Or if you want more pop...get the S&W .38 Special Bodyguard revolver. It also has a integral Crimson Trace laser. My wife carries that one. Nice little piece.
I have a Veridian green laser on my Glock. It’s riding in a Kydex holster designed for such an arrangement.
