9x25mm Dillon would give you a way better chance of penetrating soft armor but your best option with a hand gun is going to be training for failure to stop. There are many reasons for which one or more hits to the chest might not stop a threat and all of them are remedied by a hit to the CNS....

....except for unstoppable robot killers from the future. The only thing that stops them is a phased plasma rifle in the 40 watt range.

This. 9x25 = AP happiness

Velocity is the key to penetrating hard body armor. for soft body armor using a pistol, you need a very hard very pointy projectile to push aside the fabric threads. I imagine that there a ration of velocity to the diameter of the projectile, with the smaller the projectile the lower the velocity required to penetrate.

I imagine a brass inverted cone would do the trick really nicely, but thats well into the realm of custom lathe work.

Such a projectile made for a pistol would also be very illegal under federal law for most people.

Bottom line if you are going to be in a fight with armored personnel, bring a rifle and shoot often and early.
