“My Colt has a Remington Serial Number. What’s Going On?” It’s the most “frequently asked question” on The Sight M1911. People often suspect that there’s an error in the serialization tables or that they have stumbled onto a rare collector’s item. Neither of these is the case, however. These guns are “arsenal rebuilds.” This term refers to guns which have been extensively repaired or reconditioned by government armorers at one of the government arsenals which support the small arms of the Armed Forces.

Government armorers had one and only one concern: to get guns back into service. They didn’t care about gun collectors. One of the great assets of the M1911 pistols – total parts interchangeability – becomes a real trap for collectors of government issue pistols. A Remington Rand slide will fit on a Springfield Armory frame just fine.

When a pistol became worn or was damaged, they were repaired or refurbished at U.S. arsenals and service depots. This began in the 20’s soon after the pistols were initially issued. During WWII, large numbers of M1911 pistols produced during WWI were refinished and reconditioned. These can be easily identified because they were parkerized and given bakelite grips. There were no parkerized M1911 pistols issued. They were all blued originally and they had walnut grips. M1911A1 pistols were parkerized originally and had bakelite grips. Also, there were no M1911 or M1911A1 G.I. pistols produced with nickel finishes. So right away, if your serial number says it’s a 1918 Colt, and it has a parkerized finish, you know that you have an arsenal rebuild. If it is a G.I. pistol and has a nickel finish, it is not original and the collector value is severely diminished. The last new Colt M1911A1 pistols were purchased in 1945, but the pistols served another 37 years. Needless to say, a lot of repair and refurbishing needed to be done.

When a pistol was rebuilt at an arsenal or service depot, it was generally marked with the initials of the arsenal. Usually, when a pistol went through this process, it was inspected for serviceability by an inspector who stamped his initials on the gun once it passed muster. Consequently, much can be learned about the pistol’s history by examining the arsenal and inspector marks on the gun.

One final note: just because a gun is an arsenal rebuild, doesn’t mean it isn’t collectible. These guns are rich in history. They may not have the high price tag of a pristine Remington-UMC, but they represent a moment in time when the nation was in peril and these old warhorses answered the call.
