Good points on the limits of the 1911. I'll leave that one alone. I am surprised that folks consider a 44 Rem Mag easier to manage than a 10mm 1911. I haven't shot them side by side, but I would think the opposite myself. Apart from the platform, let's just say we got a 300gr hard cast 40cal bullet to 1000fps in a comfortable semi auto. Not a free lunch, just the size of a Mark 23 and a robust design with 10-14rd capacity. Call it a unicorn if you want, let's just pretend I found one. Would that seem like a solid choice ballistically?
