The 1911 platform as a whole, no matter the caliber, was designed to run on ball ammo. Companies have tweaked the recoil spring weight, feed lips, mag spring weights, etc. to try and avoid most feeding issues in general, but overall it comes down to the profile of the projectile. Sometimes you find guns that eat everything, like my PT-92. But every now and then you get one that hates steel cased ammo, or doesn't like the profile of say a Remington JHP's while it feeds say Winchester JHP's just fine.
Any way about it, it's always a gamble how any firearm handles one ammo versus another. No matter what the platform or name etched on the slide.
