Because of the shortage of good SD ammo & guns, the 10mm would probably not be my 1st choice. I would certainly have no issue carry my Delta but the same gun in 45acp is just as good for SD/HD, easier to shoot & a lot ofammo choices. If I patroled the woods as a LEO, then the 10mm makes a lot of sense. Of course then you don't have to worry about ammo cost or selection.
IMO, over penetration should not be dismissed, but more important is can you deliver ALL your shots w/o a miss. A miss will be far more dangerous than overpenetration.
"Given adequate penetration, a larger diameter bullet will have an edge in wounding effectiveness. It will damage a blood vessel the smaller projectile barely misses. The larger permanent cavity may lead to faster blood loss. Although such an edge clearly exists, its significance cannot be quantified".
