Loaded with 7 in the magazine and one in the chamber (how it's carried) it comes in under 9.5 ounces. That's my Samsung i-760 next to it; the P32 is the SAME thickness as the i-760. It's TINY, but very potent. My hand completely covers the firearm (and I'm not that big of a guy).
Kel Tec makes a 380 (P3AT) that's the same size, but that little thing really kicks and roars; the 32 is tamed down enough in this weight/size that I have yet to find a woman who's intimidated by it, when shooting (can't say the same about some of the bigger firearms I have, or even the old S&W model 36 "pocket revolver" that is 3X the weight).
Still love the 380 though - a VERY capable caliber, plenty of bark too when fired; it DEMANDS attention! Personally I'm like you - give me a firearm that is on hand all the time, and is reliable and I'm happy. Something tiny like this or your SIG 232 just disappears in about any clothes this side of a Speedo (and believe me, if I was wearing a Speedo I wouldn't need a firearm; the bad guys would simply fall over retching from the view!).
