I have to agree with rn-cindy's choice here, the best bullet to use is the most effective. From what I have found(no I don't do my own FBI criteria testing), the Federal 124 gr. HST is the most consistent performer in the 9mm loadings available on the market today. If you know how your bullet is likely to perform, you can use your best judgement on ballistics of the round.
Here's another good option if you're worried about over penetration.
