Since Rex mentioned 1911 builds, I thought it only fair to point out that some of the guys on the 1911 forum (aka M1911.org) actually are "building" a 1911 and making it available to their forum members. Last time I lurked...er looked, it was about ready to go into production.

You will find a review of their prototype here http://ezine.m1911.org/showthread.php?t=18.
