"Springfield Armory is the oldest manufacturer of military arms in the USA. It was commissioned by President George Washington. SA has almost silently evolved as the preeminent 1911-A1 handgun maker in the world."
The only problem with that is...
Springfield Armory, located in Springfield, Massachusetts, which supplied military firearms for almost two centuries, has NOTHING to do with Springfield Armory, the current manufacturer of rifles and handguns.
The military installation closed as a manufacturer in 1968. It is now operated as a National Historic Site and museum.
Springfield Armory, located in Illinois, is a purely commercial firm that shares only the name with the former military installation.
