Kind of the worst of all worlds, all in one!

That was the older JHP from the 90s. My understanding was that it wasn't designed for expansion, but was intended for use in suppressed pistols and submachine guns.
The current crop of 9mm 147gr JHP are all good to go as far as penetration and expansion. My defensive load of choice is 147gr HST.
However, since those early 147gr JHP didn't expand, their performance would likely mimic FMJ of the same weight, so in that light it seems like maybe 147gr FMJ would still be an overpenetrating round.
Thanks for sharing.
