Personally, I carry a 1911 in .45 Auto, so if I hit a bad guy with one shot in the hand it picks him up and throws him across the room, so I don't know about the "underpowered" stuff ...
Seriously, FMJ in any of the common handgun calibers has a very good chance of over-penetrating ... shooting right through the intended target, and possibly also wounding an innocent person beyond. What we want in a self-defense round is for ALL the bullet's energy to be dissipated in the intended target. That's what modern hollow-point ammunition is designed and intended to do. The expansion creates a larger wound channel, plus the expansion helps prevent over-penetration while maximizing the amount of energy dissipated into the target.
