Searching for a full barrel specification for usage outside of TFB, I stumbled across this gem of a forum post from GunSmithInfo.com. Posted up for all to see in great clarity is the full Government 1911 prints, for every part including full readable notes, sizes, tolerances, and likely testing methods.

The post is a veritable gold-mine for those looking to either do it themselves or start up manufacturing the handguns. Heck, I downloaded the entire parts list just for posterity.

Those interested can hit the link here.
