My Aunt has a Beretta tip-up barrel pistol in 22 short. Tiny little thing and a true pocket gun. I shot a Tomcat in 32 acp a while back. Even with the smaller caliber, it is a fat pistol compared to a lot of the newer 380's. The advantage of those Beretta designs is they are all steel or alloy and work very well. You could also just jump to the Beretta 84 or 85 in 380, but they are not as small. The 84 has a 13 round mag, though I like the CZ 83 better.
My SIL has a Sig 238 in 380. It is her every day carry gun. She loves it.
