I remember the days when a box-stock Colt worked better with ball than some of the early hollowpoints. The magazine lip designs had something to do with that, too.
Nowadays, with better magazines and ammunition being available, I only use ball loads for some occasional training/practice.
I don't carry .45 ball in my .45 pistols for the same reason I don't carry LRN or ball in my .38's. There are much better options available.
I can understand the nostalgic allure of some shooters wanting to remain with .45 ball, but that doesn't mean it might turn out to be a good decision at some point down the road, if they really have to use it as a defensive weapon.
My dad (Korean War generation) used to keep his Gov Mdl loaded with the old Rem MC SWC target load, as that gun had been tuned to feed it by a Border Patrol gunsmith. He liked the wider flat point compared to ball. He also liked 200gr LSWC loads. Ball was his last choice. I still have a couple rounds he gave me of an old Norma .45 ACP load which used what appeared to be a revolver JHP, with lots of exposed lead around the nose cavity.
Perforations (also called "over-penetrations") of an intended threat target can happen, even with JHP's (and especially if hits occur in peripheral, shallow areas of the anatomy), and misses with any bullet design are still ...
misses.
Training & practice ... training & practice ... training & practice ... and the use of the best of the modern hollowpoint ammo someone can afford may still be helpful and a "better choice" than ball ammo (presuming it's lawful in the user's area).
Then again, some folks might still get their gun advice from Mike Hammer novels.

liked those books growing up, myself.
