A friend of mine posted this comment on instagram a while back so I thought I would share:
"Velocity is a key factor to the overall extent of gun shot wound injuries. According to the kinetic energy equation (kinetic energy=mass/2xvelocity squared) doubling the mass doubles the energy. However doubling the velocity quadruples the energy. Therefore a small-caliber bullet traveling at high speed can produce a more extensive injury than a larger caliber bullet traveling at a slower speed."
So I do agree with you that over penetration can be a problem for some with the 9mm round so it's not for everyone, especially if their handgun isn't rated to be able to shoot +p consistently without replacing parts. But it WILL do more damage.
Now you can't get +p in 40 but many love the extra velocity in 45 being that it's a slower round.
It has it's positives and negatives just like anything else. But to the OP, I will always recommend that you do NOT use +p or +p+ rounds consistantly at the range, because regardless of the gun (in most cases) it will wear down faster than usual.
