My limited perspective...
I've shot thousands of 45acp rounds from steel framed 1911s, both government and commander models, and never thought the recoil was an issue.
I've shot a few magazines of 40s&w through a pal's Glock, and didn't feel the recoil was bad at all.
I have an alloy framed Colt 1911 lightweight commander in 45acp and I definitely notice the recoil on that one, but still wouldn't consider it to be a big deal.
The recoil that has me thinking "ouch" is 38+P out of my airweight snub.
