To keep my annual certification up for nationwide carry, I bought a Sig 232 and used it at the range instead of my Sig 229, which is worn from years of service duty. The 232 gave me a perfect score each session, at distances up to 25 yards. I stupidly traded it off when a penetration test into wet phonebooks revealed that I only needed one phonebook to test a .380. A weak cartridge, to be sure, when compared to what "on duty" folks carry; however, for a retired cop who isn't enforcing the law, and for anyone who simply needs to save himself in an extreme emergency, I think a .380 is enough, especially considering carry time compared to acutal need.
The next gun I buy will be a Sig 232 with night sights, and I intend to stop toting the heavier calibers.
Further testimony in favor of a Sig 232: I have a Ruger LCP .380. It functions fine, it's easy to carry in a pocket, but it has very limited range compared to a 232. While the 232 can keep all rounds in the head of a sillouette target at 25 yards, the LCP will not regularly hit the target at all at that distance.
