Going to carry a cz-52 or TT-33 are you? Well, This round has a good reputation for doing some serious damage, it also has a reputation for over penetrating. 2-3 years ago it would have been considered one of the worse rounds for self defence, because of its guarantee to pass right through the human body, but now-a-days hollow points and soft points can be seen for sale. The high velocity makes the bullets the best canidates for expansion, and the muzzle energy is better than any other caliber up to .357 magnum, including 45 acp.
You can buy hollow points here:

And as for ballistic tests, well, I have seen this round penetrate steel piping, if you are going to use this caliber for self defence it'll be hollow points only.
On left 7.62x25...on right 9MM
