It sounds like he confused the Sig P230/232 series with the HK P7/P7M8 series. The P7 (and PSP) had a heel release, but the P7M8 sports a release in the American position.Obviously...that is not correct
Interestingly enough, the P7 is about the same size as the P232, carries more rounds, and the rounds are 9mm. If I was allowed to carry my P7, I would faaaaaaar prefer it to the P232, pretty much for those reasons (and the sweet trigger).
That said, I like my P232 as well.
