The rounds i keep in my .32 auto pocket pistol are Elmer Keith style bullets. I'm sure it's a role he never envisoned his bullets filling! Turns out that in .32 auto the #1 thing that people who carry them worry about is penetration, not expansion. The "Buffalo Bore" loaded Keith bullets in .32 will penetrate 15.5" of ballistics gelatin, more than a lot of full power defensive rounds in much larger calibers.
