I agree (1) that too little penetration is bad. And (2) alleged "over penetration" I don't worry about.
But, having seen BG's stopped instantly with one shallow penetrating COM pistol bullet, I know that there is more to "stopping power" than deep +12" penetration. Whether it's called shock, or stopping power, or whatever, it exists and isn't a myth.
If not, maybe the FBI can explain why deep penetrating .38 special 158gr RNL bullets don't have much stopping power, but much shallower penetrating .357 mag 125gr JHP's do?
Luckily, 10mm full-velocity ammo in the heavier weights have both deep penetration and decisive stopping power.
Cases do exist where the 125 fails to adequately penetrate the vitals of a thick body.
Light and fast may work better than slow and heavy and vice-versa depending on the body type. This is why I choose heavy and fast. 10mm cant loose in either case.
XTP's at Double Tap 10mm velocity will actually perform more like a controlled expansion bullet in real tissue. Gold Dots at 10mm velocities may do fine in ballistic gel - but in tissue and bone - they may over expand (according to Ferrel dog shootings).
I see no problem with combat distances and 10mm DT XTP's.... Beyond 21 feet, the 10mm may lose enough velocity where over penetration becomes a concern with XTPs. Load up with XTP's and push them as fast as you can!
