Back when I started working up loads in my Colt Series 70 Mk.IV 1911, prepped for 45 Super, I set 10.4gr/Power Pistol as it's max load using a HDY 200gr XTP bullet, CCI-300 primer & 1.200" COAL in S-L 45 Super cases.
FWIW,
QuickLoad calculates this at 1211mv & 652me @ 26.8K psi from a 5" bbl. (Pressure drops to 25.0K psi & mv to 1190 with a 1.220" COAL.)
This was backed down from 10.8gr/P-P because the unsupported chamber's mouth would bulge cases.
I use this in my 4506 & 4586 as well even though their fully supported chambers are good for more. I like the way the S&Ws handle the recoil (feel) better than the 1911.
Work-up slow & use at your own risk.
