The National Park Service (NPS), which operates the Springfield Armory National Historic Site, is the official source for production data from the original federal armory.
This is the original government facility located in Springfield, Massachusetts. They produced some of the most iconic firearms in American history, including the Trapdoor Springfield, the M1903, the M1 Garand, and the M14.
The M1 Garand is one of the most documented military rifles in history. The National Park Service maintains a month-by-month production record for the M1 Garand.
Determining the exact manufacturing date, model, and history of a Springfield Armory firearm requires a deep dive into its serial number. Whether you own a vintage M1 Garand from the original government arsenal or a modern XD pistol from the contemporary commercial entity, tracking the serial number unlocks vital information about your firearm.
