both, mixed in the same mag
JHP in the gun, back up mag with FMJ

I would go under the "both, at whichever time is convienent" category as well, however I do things a bit differently.
If I just picked up a new .45, I usually grab a few different boxes of ammo for testing. Gold Dots are my round of choice, but the damn things are $20 for a box! Theres no way I can test reliability on all self defense ammo at once, so I usually will grab a box of Hydra-Shoks, Gold Dots, WWB, Lawman FMJ, and some Remington UMC. I run it all through there, making sure the Gold Dots and such work, taking note of accuracy. I also like to mix it up a bit to see how well it can do with feeding inconsistencies. If it hangs up, I note which type of bullet it was.
After I've used that ~$60 in ammo, I load it with the best grouping FMJ's until I can afford another round of boxes of HP's to run through it. I won't trust ANY ammo after running just 20 rounds through my pistol! For any HP round, I have to fire at least 50 rounds of the stuff to trust it in that particular weapon. Until then, its FMJ. .45 makes a good hole, and even the FMJs have good but not extreme penetration qualities. It IS a .45, after all! Its not exactly a high velocity long range round.
Right now my full size has Golden Sabers and my Commander has Hydrashocks. Eventually when I can get the time on the range I will standardize on something they both like.

remember the only thing common about common sense is that its not that common
Shoot low boys their riding Shetland ponies.
I carry Winchester 230 grain SXTs in my Commander, 100% reliable.
When you’re wounded and left on Afghanistan’s plains,
And the women come out to cut up what remains,
Just roll to your rifle and blow out your brains,
And go to your God like a soldier.

I think, therefore I am armed.
+1I carry Cor-Bon DPX (185gr +P). Since it uses a solid copper bullet, it's technically not a jacketed hollowpoint, but it is a hollowpoint so I voted JHP in the poll.
Also in my mind even if we forgo the hitting a second person argument, I want to use hollow points because if the bullet does exit that is a significant amount of energy wasted behind the target, energy that should have been dumped in the target. IMHO

Penetration with FMJs IS optimal.
Let's put it his way: Optimal penetration does not necessarily mean over penetration.
The human body is full of all kinds of bullet traps, both the soft and the hard.
I'm simply not sure of what it is that you find confusing.
Over penetration and optimal penetration can easily be perceived as the same thing.
Anyway, we're threadjacking now. I'm just a guy on the web, ignore me...
Whatever - each of us is betting our life on the gun and ammo we carry. My life. My choice. I never try to convince anyone to use a certain kind of ammo. Besides, it takes practice to bring a .45 shooting 230 grain FMJs back on target quickly. Most people who carry do not practice any where near on a regular basis. That observation is drawn from experience I've had with the many people I know who carry concealed. Carrying concealed is rather common in Indiana.
Believe me, I wasn't being short with you. I simply didn't understand what you were getting at.
I voted JHP but generally carry a Glaser in the pipe and corbon DPX or Powerball in the magazine. Don't know those are technically JHP but I know they aren't FMJ.
Let me put this out there, and you all can then debate this.
Part of my reason for this poll/thread, a guy I know, ran some experiments with .45 HP ammo on targets that were dressed. His end results showed that most .45 HP ammo did NOT expand. The primary reason was the cloth filled up the cavity.
This got me to thinking, if this is really the end result, why bother with HP ammo in a .45? After all, FMJ was good enough for the military, and for a very long time, it was still the preferred ammo for most civilian use, at least until most of the newer stuff came out.
AND, as has been pointed out, over penetration for the .45 has been "over hyped."
