Guess I'll be one of the odd ones, as usual. :mellow:
I carry hollow point AND FMJ rounds in the same magazine. Chambered round is HP and first couple of rounds in the mag are as well, followed by FMJ.
Depending on what full-sized sidearm I carry, the first 8 rounds (for the 16+1 CZ 75B) or 5 rounds (for the time-tested 1911-A1) may be HPs, followed by FMJ.
Only carry FMJ in the PT-111 G2. The short barrel already robs the bullets of velocity, so why stack the odds any further in favor of under-penetration? :-\
Rationale:
First few shots likely need to do the most damage in the least amount of time to STOP THE THREAT. Whether they expend all their kinetic energy inside the criminal or manage to make a (messy) exit wound, these first shots would be the most critical.
Next couple of shots are there for penetration. Yes, I said it. A bad word, I know (not that way! Pre-vert

) Two holes per bullet* should be considered a good thing in terms of stopping power. Mind you, the bullet shouldn't just be flying through the criminal. Chances are it will be slowed down as it passes through soft tissue and bone.
Maybe the criminal(s) is/are behind cover or have flak vests on. Maybe their clothing just happens to be thick enough that the bullets aren't penetrating deep enough.
Just my opinion. I've heard of folks who simply alternated HP, FMJ, HP, FMJ, HP, FMJ, HP, FMJ....
*Without getting too far into it, I'm pretty sure over-penetration of Center-of-mass hits with commonly-carried sidearms is a myth. Yes, it may be a possibility for a heavy .357 or .44 load paired with a 6" barrel, but not likely for pocket pistols, snubbies, etc. If we're talking about a shot that goes through a hand or such other thin areas, then a HP would probably have zipped right through as well with enough kinetic energy to hurt someone else in the flight path. Kinda goes back to the "Know your target and what lies beyond it".
