1911 Original Blueprints – Gunsmithinfo.com

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.

    I’m not sure it’s a 100% original John Browning from year 1911. The blueprints are signed and dated 15DEC55.

      It doesn’t say “John Browning’s Original” Just they are “Original” blue prints. If you follow the link and look at the drawling you’ll notice some are from “Dept of the Army Rock Island Arsenal” and others are from “US Army Armament Research and Development Command” not all have the original drawling date of 15DEC55. Some are 4FED55 others 15MAR55 still others are from 1MAY28.

    That’s awesome!
    I’m going to go ahead and make a hardcopy binder with all the prints for some coffee table literature.

    Cool, now can we get other manufacturers to start making them loose instead everyone trying to make a tight fitted 1911 that may not be reliable?
