I'm no engineer either, but my best guess would have to do with the 380 operating at a max of 21,500psi while the 9mm operates at a max of 35,000psi.

While it may not be possible to make an LCP sized gun in 9mm, the Kahr PM-9 comes pretty close though it weighs twice as much (there's that pressure thing again).
