it is not gender specific, all CCW guns are compromises
You already have a nine, we presume a tad large for CCW
too crudely, too loosely stated same 9mm at half the size & weight will kick about twice as hard
single stack small pistols are slimmer, easier to carry
which is why the little 380acp pocket pistols like Ruger LCP and KelTecs are so popular with so many, including a lot of "big guys"
they are not easy guns to shoot well, though, best thought of as 7-shot derringers
airweight 38 snubbies are mean to shoot w/ 357 and 38+P
the smaller the handgun, the harder it is to shoot really well with (translation, lots of practice)
compromises, compromises you have to choose your own
power vs. size/weight/carry comfort
but if somewhat familiar with semi-auto pistols, and if not opposed to limited power in smaller packages, you could take a 1st person look at Beretta Tomcat in 32acp, Ruger LCP 380acp, bunch of that stuff is out there to look at
(after all, if you can carry a 3" Ruger SP101 or a 4" k-frame in your purse, you could probably just carry your nine in your purse)
