All the 9mm ball I own comes to a pretty definite point. More so than say, .45 ball which has a very rounded nose. The 9mm stuff is a lot more pointed and certainly gives the impression that in ball configuration, it would be a good penetrator. I can't say it would out penetrate the .44 mag, but my experience with the .44 mag is with jacketed soft points or cast, and shooting against thick steel, the 9mm certainly craters the metal significantly, while the .44 causes a very large, round dent.
I don't have any steel thin enough for either of them to penetrate, so I can't definitively say one will go through where the other doesn't.
