CMP 1911 identification help

[hundy]

I finally received my M1911 from the CMP. It is a Remington Rand receiver (1944) this was a field model as no service models were available. I have not been able to ID the slide. It has the number 7790314 on the slide. The lower receiver is stamped "A U A D 4 87". I am guessing that means some kind of upgrade was done in 04/87. If anyone has any information I would appreciate it.

Thank you,

Jay

The slide is also not original if it has a drawing number on the
side, usually 7790314. These are replacement slides made long after
WWII by Colt and SanColMar. The same is true if the slide is marked
Drake - the company that built National Match slides for the
government.

Could the stamp be ANAD? I believe Anniston used the ANAD stamp and the 4 87 could be the refurb date.

Yes that is ANAD

Looks like a post-war contract slide, very probably fully hardened which is awesome if you plan to shoot it!

Correct I do believe it is ANAD. It is hard to tell but I do believe that is it. Most of the markings are so hard to read that it took 3 of us to confirm the serial number at my FFL during DROS. Thank you for all the information. I was able to take it out and fire it and it a very good firearm considering its age.
Thank you again,

New fashioned old fashioned trick that helps with picking up markings more often than not... take a picture of it with your phone, then you can zoom in and sometimes read it much better than with the naked eye, or often even better than with glasses or a magnifying glass.

Great pistol. I'd shoot the heck out of it!

Considering the amount of rounds fired through GI slides from WW2 to the 90s without problems, I doubt slide failure is a major concern. The problem I saw in the Army was frames cracking through the rail at the slide hold open cut out.
