Among the JHP's, there are 2 approaches that I think are viable for 9mm. Against minimal clothing, the Nosler 115 gr. JHP can be very nasty. Within about 3 or 4" of penetration, the bullet breaks up into several small pieces. Normally, I find that one piece and the jacket are left in the first 1 gal. water jug, and 4 or 5 pieces penetrate into the 2nd. I shot a jackrabbit one night that was standing at the front of my car with that bullet. As I got out to see the damage, I found one little side of ribs on the car roof. That was loaded with 6.5 gr. of Unique and a Rem. small rifle bench rest primer.
The other design I like is either the standard Rem. 124 gr. HP or their 124 gr. Golden Saber. Check the gel test results:

In water, I find that the standard Rem. 124 gr. HP actually retains the jacket better, and expands about the same, fully traversing 3 separate gallon jugs.
With the Nosler bullet, there is a lot of internal cutting and no exit. With the Rem. bullets, I would expect a nasty exit wound, with heavy bleeding. The Rem. bullets would be the better choice for penetration of any clothing or gear. That's as destructive as the 9mm can be.
*Note that I don't discredit the Nosler bullet for fragmenting. What this does, in the real world, is create a larger wound, because the fragments don't just sit there! How deep into the body are the vitals on a man? If you have 5 separate fragments, each traveling 4 to 6 inches after penetration and in different paths, your boy is going down!
