I had over a dozen mags when I had my 1911s and neither gun would feed hollowpoints with any reliability. My AMT would feed a SWC I seated out to a long enough OAL that it head spaced on the rifling, but still fired okay. I had both guns throated and polished by a good gunsmith, too.
The newer designs have a more straight in mag to chamber path, less, if any, time spent on the feed ramp. That P90 will feed an empty case without a burp! That, and the feed ramp is one piece integral with the barrel which helps a lot, too.
I see 1911s as tinkerer's guns or great high end guns, but I'm not ever playing the cheap 1911 thing again and I can't advise anyone to unless they're just looking for a good, cheap platform to build on. I know there were some well known smiths building high end guns on the Norinco platform, tells me the basic gun just needed the fine touches.
I found out I ain't got the patience to be a 1911 tinkerer and am no gunsmith. I could learn, I reckon, but I don't have the desire and don't wanna buy all the tools and I'm not a machinist, either.
Just me, but I ain't wastin' another dime on a cheap 1911. I've seen a lot of good ones in the hands of good shooters, but something tells me they might not have been cheap or out of the box and I owned junk. LOL! Ah, they worked and the AMT was accurate, so long as you didn't drift too far from hardball. It seemed to like my SWC after I seated it out to the riflings. That bullet has a nice rounded shaped nose to it, probably because it's for .45ACP and the bullet mold designer knew something.
It's a 200 grain Lee Tumble Lube mold, good bullet for picky 1911s and it shoots well in my P90.
