The issue with 38 super is the semi-rim. I understand (and can easily visualize) what's described as "rim lock".If you want a 9mm 1911 it is not my choice, 9mm Glock 19, or 17 I’d great platform for 9mm ammo.
If you’re wanting 1911 in non .45 ACP, think about .38 Super. Bullet is same length as .45 ACP, so 1911’s in .38 Super work & run well.
I've evolved to having a preference for 357 Mag revolvers. The simplicity, reliability, choice of load, and raw POWER is hard to top in one package. And I'm gradually getting rid of my small number of gun. The last one I'll keep is a 357.
Just my two cents, not really answering the question, am I?
Gulp...
