Hi,

I'm looking for blueprint or drawings for Colt 1911 Officer Model or compatible compact 1911s that have the same frame size. However after a full day's search I was not able to find any.

Could you point me to the right direction where I can find such a blueprint/drawing?

The most important thing for me is to find out spacing between the centers of the two grip screw bushings, and also the shape and width of the handle.

Any help will be very much appreciated.

Terry

Hi Boom Bam Whamo,

Thanks, but Page 46 of M1911 Full Blueprints is the Front Sight of M1911A1.

I'm looking for blueprint for Colt 1911 Officer Model (shorter grips), complete or frame only.

Hello,

FWIW Kuhnhausen Vol II is no help. It only shows full sized 45s.

I don't think you will ever find a blueprint for a 1911 part other than a full-sized one. That's probably because they are all the property of Colt and not in the public domain like the Army Ordnance blueprints in our Tech Issues section.

You might be able to come across some individual's rendition of, say, a Officer's Model frame but it's nothing more than that - somebody's rendition.

If you really wanted the official Colt blueprint for an Officer's Model frame you would need to engage in some industrial espionage. And we won't post your bail! :D

Well, thanks for pointing that out. I plan to plant a mole in Colt in the near future so maybe I will get my hands on the blueprint in maybe 5 years..........

Seriously, I will need some help from members who has a frame of the Officer Model. I need the measurement of spacing between the centers of the two grip bushings. It must be measured very precisely, though.

Thanks again in advance for any help.

Perhaps your company might be able to obtain the official bushing spacing if a formal request is made to Colt? But I'm guessing that's already been done and denied (or ignored) and that's why you're here. I'd be happy to oblige, but have no Officer's model to measure.

Lots of forum members have Officer's Models, and one of them will probably soon chime in with some sort of measurement - hopefully an accurate one (like the raw data distances between the insides and outsides of the bushings on both sides of the frame).

M15 General Officer Pistol blueprints should be available through a FOIA @ Rock Island Arsenal. Jerry Kunhausen list all the specific blueprints in his volume 2 about the M1911/M1911A1 pistol.

Is someone want to give it a try, I should be able to find my book & list the parts.

The M15 is a different animal from an Officers. A genuine military issue of about 1000.

Best,

You are correct, Jon. However, the true Colt Officer's ACP drawings are proprietary and not likely to ever be publicly available—at least not legally—if I know Carlton Chen, Colt's General Counsel, as well as I think I do. The M15 drawings are the only ones in the public domain, methinks.

Certainly one can backwards engineer the OACP and prepare drawings. However, the dimensions and tolerances will be a "best guess" only.

Also, the M15 General Officers Model does not have the shortened grip of the Officers ACP, nor the 3-1/2" barrel and slide. The M15 is dimensionally the same as a Commander, but has some internal differences.
