While you are right that the formula for piercing soft body armor is surface area and velocity, NO handgun short of a FiveseveN with proper ammo should be considered reliable at piercing soft bodyarmor, and even then the effectiveness of the round is somewhat in question.
That being said, if you expect to run into guys wearing body armor, then the alternative should be a headshot.
The point though, is really what level can you comfortably carry and conceal and what type of handgun can you handle the best.
