Interesting concept - but would the 1911 frame 'take it'?

Mine cracked just from using sized down .45/90 bullets, 300gr., bullets at 800fps with top-end blue-dot loads. Sure was hell on my plate rack - they'd re-set themselves as they bounced back off the stop bar. I check-drilled the crack and it was find after that- same loads.

I remember reading about the Rowland many years ago, but do not remember what gun it was made up on.
