Probably most of the Colt aficionados on M1911.org know that there are available on the Internet copies of the U.S. Ordnance Department "blueprints" (they are actually blackline prints on white paper, but everyone refers to the as "blueprints") for the M1911A1 pistol. Over the years, some people have wondered just what's different between the M1911A1 and the Officers ACP pistol. Sure it has a shorter barrel and a shorter handle on the receiver, but what else is different?
Harwood Loomis, John's co-editor for and frequent contributor to the M1911.org on-line magazine has just completed a task that took him roughly a decade -- he has generated a fresh set of "blueprints" in the same format as the Ordnance Department prints, but reverse engineered to reflect all the parts that make up the Officers ACP pistol. Having completed the task, he is now trying to see if anyone cares. If any of our members would be interested, please post here. And, if you are interested, please tell us what format you would prefer. At the moment everything is in PDF format, formatted to print on 11x17 (ledger, or tabloid) paper.
Please let us know if there's any interest.
