There are also many who worry about over penetration.

I discount this because in a gun fight most shots miss and I contend that the ones that miss are more lethal than the ones that may go clear through the bad guy and then go on down field.

I live in a house that is very close to my neighbors' houses. I don't want a bullet to go through my wall and theirs, then through a neighbor. For this reason I don't ever load FMJs when I am at home. I shoot a .45 Colt, but even with this large (and slow) round, hollowpoints won't penetrate a wall. 410bore #7 shot definitely won't kill a neighbor, nor will 000 buckshot.
This is the only scenario where I worry about over-penetration.
