When I was at the range at couple of weeks ago I struck up a conversation with the guy at the bench next to me, actually he started it 'cause we both had the same Savage .22, blah blah blah.
After a while he produced his Kimber (which doesn't do a whole lot for me, but 1911's do ) and proceeded to demonstrate its operation.
I have no idea how to describe in technical terms how this thing worked. Basically, he carried the piece with the hammer down with the safety up (or on). When it comes time for presentation he would thumb the safety which then cocked the hammer. Ready for action. To drop the hammer you merely apply a little bit of pressure with your thumb and it "drops".
Coolest thing I have ever seen. Don't know what you call it but he said the job was done by Cylinder & Slide.
Just a thought.
