============
I have some time while in covid isolation.
So let me elaborate.
My little colt is a nifty officer's model.
I have vetted it in competition and therefore trusted it enough to carry on a mainland trip.
The old 1911 geometry was never designed to feed hollow point ammo.
So when I shot it in competition, I only used 230 gr. RN.
It performed reliably and accurately as well. In fact, there was actually a stage where the IPSC target was set at about 40 or 50 yards.
The time limit was generous enough to allow me to drop to the roll-over prone position and engage.
The RO was impressed with the hits. LOL
IIRC I actually won a pretty nice prize for that match.
The point I'm trying to make is that the old 1911 platform is a fine defensive pistol, but I would never trust it with hollow point ammo.

I would trust the newer generation of polymer 45 auto pistols with HP ammo. They seem to have better feed geometry.

I encourage everyone to vet their defensive pistol with actual hollow pt ammo or at least a reasonable facsimile thereof.

I just bought some JHP ammo and some JHP bullets to reload.
we'll see how it does in my 1911's but I really got it for my polymer 45's.  but I want to see how it feeds in my 1911's too

you got a chrono, yeah?
recoil impulse absolutely affects feed reliability

yes, I have a chrono.  but haven't used it yet.  too lazy to set it up.   
but I should use it
I got 45acp gold dot 230grain and HST 230 grain, and some projectiles on the way 230 grain JHP and 185 grain JHP
also got some XTP 200 grain that I have not tried yet
also got a butt-load of Montana gold 230 grain JHP that I haven't tried yet.  I had it for years
plenty of 45acp brass.  I'm tripping over all the supplies in my bedroom. too much buying and not enough reloading

===================
you could do a little science project like what I did for the 9mm gold dots.
Dissect, test and duplicate

I did that for 45 mil ball many years ago too.
I settled on about 5.8 gr 231/hp38 to simulate mil ball ammo.

I have 231 and hp38 and titegroup and accurate #5
I'll do the project bc I love me some 45acp. 'Murica! 🇺🇸
