One could presume that when fired from a pistol with a longer barrel, that the performance improves even more.
Personally, I like more penetration, since the desired depth is 15". Thus, I use FMJ-FP in .380, which get 16-17".
If you are going to make such statements on this forum to a newbie (based on number of posts) then please support your assertions with some facts.

In the 357sig tests I've done... The Remington golden saber bonded seems to be a comparable penetrator to the DPX. They both don't expand as much as the PDX1, HST, 5 petal gold dot and some others.

It was interesting to see most other tests many by the manufactures and some from gel tests online... That the rounds penetration compared to others coralated strongly to the expansion charictoristics of the rounds.
If I want penetration in 357sig... The golden sabor looks to be comparable to the dpx.... Although... I haven't done hard barrier testing yet...
A third place goes to the 6 petal gold dot for penetration. The 5 petal version has maximum expansion close to the HST from what I've seen for comparison and give up some penetration for extra expansion.
Guess I'll have to add some more pics showing this to my 357 sig wetpack test thread now....

I been a 115gr FMJ 9mm fan for decades. Can't see a reason to change.

In an emergency I will take anything over nothing in my arsenal ..... Be it a FMJ or HP , 22, 9mm, 12 Ga ....bottom line it's gonna hurt , then you will have to contend with my dog then me ....and what ever you do don't piss off my wife :) that's really gonna hurt .

Why is that? 9mm ball is notorious for having poor terminal effectiveness and overpenetrating. I don't think you have to buy into the next big whiz bang JHP design but you cannot discount modern ammo technology. A solid bonded load like Gold Dot or 147 gr Winny Ranger (RA9B) will really increase the ability of the cartridge to incapacitate someone rapidly.

Unless your attacked by boneless chickens ballistic gel isn't a very accurate indicator. Most of the vital parts on humans are shrouded by some form of bony structure. Bones tend to greatly reduce penetration and you end up with far less than ballistic gel distances of penetration.
Stick with a field proven self defense round such as what law enforcement agencies use and you'll be good to go.
Speer gold dots seem to be one of the big runners in that class as do some of the Winchester rounds.

Re: 9mm ammo penetration
One of the counterintuitive things I've noticed with expanding bullets is that lower velocity does NOT necessarily mean less penetration. What sometimes seems to happen is the higher velocity round expands more and sooner causing it to slow down more rapidly and stop sooner.

Yes, that is indeed often the case.

Not much of a 9MM guy but if I were you I'd try to find some subsonic ammo. Less penetration and a little less tinitus : )

This is all you need to know about the "Overpenetration" myth.

IMHO the energy thing and "hydrostatic shock", at least in handgun rounds, is a non factor. Handguns are exceptionally weak comparatively. Rifle rounds do create large temp. cavities and that shockwave can damage tissue to an extent, but the primary wounding action is the crushing of tissue by the projectile.

A .50+ hole through your heart or lungs or head will incapacitate. All about shot placement.
