A machinist with the handle 'BullHunter' has been building a 1911 in 10mm.
   
At the beginning of the project, he posted photos and progress reports on http://forums.1911forum.com/showthread.php?t=306487
   
He disappeared from that forum and is posting at http://www.1911pro.com/forum/viewtopic.php?f=7&t=1511
   
I was curious about the final result and was lead to the 1911pro site. Looks like the build is still ongoing.

Some may know about this project, but if not, it may be of interest.
