It's basically a handheld carbine. Ridiculous flat trajectory just like the .40, but accurate out to a solid 2-300 yards. No joke, the 10 is a reach out and touch someone round.
I seem to remember reading that the .40 cal evolved from 10mm because 10mm pistols were being "shot out" in about 2000 firings.

The guns just couldn't stand up to the power of the ammo...
Thus the 10mm "short" was born.
