'Colt pistols and revolvers were stamped with a repair mark when repairs were made during and after manufacture.This was the same mark regardless of the work performed, whether simply repaired or completely overhauled. Overhaul marks were not defined in Army regulations, so variations may exist depending on the policy of each arsenal.' These initials were normally stamped on the left side of the receiver, although SA marks were generally on the right side. 'Beginning in the late 1930s, arsenal overhauled pistols were sometimes marked with the initials of the repair facility.

If anyone can identify the barrel, please advise. I have not looked up the barrel markings yet to even know what it is. I have not had it apart yet to see what markings may be inside, but I can see it is a 1944 Remington-Rand receiver with a Colt slide. I am curious how many others have 1911A1’s that have been rebuilt multiple times like this? Can anyone confirm “K” stamped on the right side of my trigger guard looks right for this? According to the Poyer book 3rd edition page 311, pistols repaired or rebuilt at Colt bear a “K” stamped on the right side of the trigger guard. In addition to this it appears my pistol may have also been repaired or rebuilt again at some point in its life by Colt. In addition to this it appears my pistol was rebuilt again at Anniston Army Depot in November of 1975 as evident by the (ANAD 11 75) stamp.

My question is, just how unique is this marking, both in terms of this shipment of 8000 CMP pistols, as well as the 1911 collector community at large? How many others have non-National Match “SA” marked 1911A1’s?

This leads me wonder if the “SA” mark on my pistol make it some what unique.

The “coolgunsite” has some images that show this marking along with some text that indicates this “SA” mark is seldom seen on NON-NATIONAL MATCH (normal military pistols) see link below:Ī quick search of the CMP Forum and internet reveals nearly every reference to 1911A1 pistols with this “SA” marking are associated with National Match pistols. The Poyer book 3rd edition page 312 says the “SA” stamp indicates it was rebuilt at Springfield Armory post 1937 and then goes on to say that Springfield Armory rebuilt 1911A1’s for National Match pistols through the 1950’s & 1960’s. I have some specific questions about the “SA” markings on the receiver. so my 1911A1 arrived the other day and I am trying to decipher all of its markings.
