When I carry my SIG 1911 w/ 5" barrel, I use the Bill Wilson Rapid Response. http://www.wilsoncombat.com/l_rapid_response.asp
It carries it very high and tight aginst the body plus it has the thumb safety guard.
I was told the holsters are made by Rafter Gunleather. http://www.raftersgunleather.com/
A warrior is a man of action, guided by reason and motivated by love!
