The grips are different on the 232, and were modified to give better ergonomics, I think. And now I think they are made of a more durable material. One small complaint about the 230 was the grips were frangible, that if you dropped the gun on a hard surface, the grips could crack or shatter, and the grips are required to hold some of the guts in that make it work, therefore, drop it in a crisis, a spring or something falls out, and no bang. That presumes a clumsy draw or awkwardness I guess. But I suppose you could always upgrade the grips, if the price difference justified it. I like the two dot or dot the I sights over the 3 dots anyway.
