I have a P230. It has fed everything without a hiccup until recently when I bought a bunch of Hydra-Shok, which it won't chamber at all. I realize that the P232 was released to address some finicky feeding issues with the P230, but my advice is to try a box before you buy in bulk.
In my experience, the size of the hole in the front isn't the issue. It's whether or not the bullet is round. Hydra-Shoks are conical, with a sharp lip at the rim of the hollow point. On my P230 this lip hangs on the seam between the lower feed ramp (on the frame) and the upper feed ramp (on the barrel.) I have a friend with a P230, and he has no problem running Hydra-Shoks through his. This indicates a manufacturing variance among similar pistols. This makes anecdotal reports of what works and what doesn't less helpful. Like I said, whatever you choose, try a box before you buy in bulk.
