Delta M1911A2's 04'-07'
I am a maintainer in the Army and suffice it to say I was tripping balls today after my find. I got to handle not one but 4 of the " M1911A2 " Project guns from the 2004-2007 " study " by Delta and the AMU. Theres virtually no info online about these and most of this info is from a very old since deleted forum and 2 listings where guns #13 & #14 sold in 2011 and 2022-23.
From what I've been able to gather, Delta put a request in to the AMU to build the best 1911s they could using off the shelf parts in 2004 and this started with 5 guns all built to different specifications. These first 5 guns ( # USPT1-5 Serial Numbers ) all had different specifications and although I don't have build sheets I was able to handle 4 of them today. All are built on Caspian frames and slides ( one of which is a Caspian Race Ready frame with a flared magwell ). Barrels are from Barsto, Storm Lake, and Ed Brown and one of the head armorers ( Charles Jenkins ) stated that most parts used were Ed Brown as well like Safeties, hammers, slide stops, ect. Triggers are a Mix of Ed Brown and Greider flat face triggers. Mainspring Housings are Smith & Alexander arched & flat mainsprings with lanyard loops except the race ready gun which has an unknown to me half-arched mainspring with an internal lanyard loop that is essentially a Stan-Chen Max Bevel to match with the frames funnel. Sights are a mix of fixed and adjustable Novaks as well as original Bomar and Trijicon bomars. Finishes ranged from a tan cerakote, an almost parkerized finish, and a glossy cerakote type finish. All frames are railed frames to accept lights.
By far the weirdest gun of the bunch was a railed frame with a slide that had an integral 1913 rail on top with a built in dovetailed front sight and a bomar rear . The original guns went to Iraq for 18 months from 04'-06' and upon return were sent in for evaluation. Though no specific contract was awarded for any of the variations, Mr. Jenkins was able to get permission to use the specifications of the guns to build 10 more pistols ( USPT #6-15 ) which is what the picture you're looking at large encapsulates. As far as I can tell the last 10 guns which were made in 07', are basically all the same pattern and some made it off the work bench and into private hands as I've found 2 sold at auction.
Markings vary on the original 5 guns such as having a circle behind the rear serrations with " US " inside or the left side of the slide saying " US Army M1911A2 ". Other guns simply have standard Caspian markings. Guns 6-15 as far as I can tell were all ordered with no markings on the slide or frame aside from Caspian markings & serial #.
Thank you for coming to my Ted talk. Unfortunately these guns reside in a warehouse away from public knowledge and the facility is a no phone area hence why I have no pictures aside from the auction listings. There are 2 clones I found on computer made by a Japanese Airsoft company ages ago but I cannot locate that website on my phone, although they are clones of 2 early guns, so if you can find it I'd be delighted.
