Good ol' fashioned Sierra JHP's from Cor Bon

Specifically the 125gr 9mm load, but applies to the others too. The Sierra JHP's expand pretty well. I know they're not "in vogue" these days but are they still considered an excellent defense round? (I realize a little fragmenting goes on with these, but hey.....:dunno:)

In 9mm, they will probably work as well as any cup/core bullet. At 357sig speeds, complete fragmentation can be expected.

One of the benefits of the .38 Super is its ability to use bullets designed for the .357 magnum; both Sierra and Hornady manuals have load data for these combinations.

This 140gr Sierra JHP (compare sectional density 180gr/10mm) exhibited excellent penetration, but fragged along the way --- mid 1200s;

A 9mm designed bullet at upper .38Super/.357SIG velocities (1450fps +) would probably self-destruct as Fred stated.

Expect rapid expansion, to the point of fragmentation. How far it will penetrate is questionable.

Follow me on this theory as it is a little convoluted: A Cor-Bon 125gr 9mm +P (if you can find these either, like all the other stuff) is supposed to do ~1250fps out of a 4" barrel. The gun in question is a Walther PPS with a 3.2" barrel, so velocity wouldn't be anywhere near 1250fps. Reduced velocity = less rapid (but still good) expansion and therefore more penetration. In other words the shorter barrel "taming" it a bit might actually work better ballistics-wise.
