P232 is a good option IMO
I personally like the 232 although I admit I have wrestled with the caliber issue as well. For me it is a trade off between good accuracy, which is most important, and power in a well refined and super thin (slide and frame) package. It is hard for me to invision a scinario were 8 rounds to the face or even center mass won't get the job done much less 1 or 2 well placed shots. The little gun is capable of that kind of precison acuracy with sufficent practice and that is what I really count on. I'm not enamorate with the 380 chambering in the least but it does afford a nice tight package for the 232 design. Kahr has come close to it but I don't trust their reliability yet. Do I carry my G19 or 1911's more often? You bet, they are without question an upgrade and my springfield is on my hip as we speak. But for me when I have to go smaller this is as small as I will go. It is accurate, reliable, very thin, I can get my whole hand on the grip, great ergonomics and is the most refined and well rounded quality 380 I have found for my purposes. YMMV!
