If small is what you want, doesn't get much smaller than a little pocket .25
I would suggest the Kel-Tec P-3AT.
It's a 6 shot double action only, concealed hammer auto in .380.
This would be a good choice for a woman. The .380 is more forgiving when it comes to recoil which leads to more practice and ACCURACY.
Accuracy is the key. I know many will say the .380 is anemic when it comes to stopping power but how many of us would want to get hit with one?
I know I wouldn't.
It will conceal better in a purse because of its lightweight and slim profile.
An additional magazine ups the power to 12 rounds.
Cost is around $300.00

have you ever actually shot a P-3AT? I own one. The recoil is anything but mild and if you can keep your shots on a small paper plate at 10 feet you are doing very good. the slide is very heavy to operate and doesn't lock open after the last round is fired so you don't only have to drop the mag and insert another you also have to manually work the slide.
Walther PPK and PPK/S are ideal for women as well. Simple field break-down in a few seconds. Small enough for a good fit in most women's hands. Also size is great for CWC.
I actually think that pistols are defined as a subset of handguns distinct from revolvers, single shots, derringers, etc. Therefore a semi auto is a pistol but a revolver is not. They are both handguns however.
And I will agree that generally speaking a revolver is easier to operate and clean. Cleaning one doesn't even require taking off the cylinder, just opening it like you would to load. Occasionally you might want to remove the grips to clean as well, but that's a pretty simple exercise too. Even very simple semi-auto designs are more complicated to take apart for cleaning.
Of semi-auto designs I have personally taken apart (a pretty limited group) I think the Sig 226 DA/SA was the simplest. Unload, lock the slide back, rotate the disassembly lever and remove the slide. From there just take the guide rod/spring off and pull out the barrel. Pretty simple. Glocks aren't too much more complicated. 1911s are a fair bit harder (still easy once you know what you are doing).
Some time ago there were a number of women taking lessons at a gun range. After the lessons they went to the range to shoot with a few handguns. Much to my surprise they did not seem to like revolvers as much as semi-auto pistols. They complained that the snubbies had too much of a kick and that the 9 mm pistols were easier on their hands!
.45's are even better. My wife says it's more of a "thump."
A revolver is a handgun, and a pistol is a handgun, but whether they should both be called pistols is often hotly debated. It's kinda' off topic so it doesn't belong here, but it is not nearly as black and white as you stated it.
For the OP's purposes, if he is shopping for a handgun for a lady, he will find that manufacturers classify their handguns as either pistols or revolvers, so it is an important detail. Pistols in this context being a semi-automatic, magazine-fed handgun in which the chamber is integrated into the barrel.
Richard, if you go looking for revolvers under the 'pistols' section of a manufacturer's web site, you won't find a single one, so be sure to check both ('pistols' and 'revolvers') for something suitable.

Snub nosed revolver. Easy to hide in their purse, simple to operate, minimum cleaning and maintenance.

Hammerless .38 revolver, can't go wrong there.
