As an interesting aside, Springfield Armory had in fact produced the components that made up the Model 1817 pistol prior to the War of 1812 (the four-year, mostly-naval conflict between the United States and Great Britain). It was only after 1815 that the assembly of the pistols was completed and made available, production now being handled by Harper's Ferry and not Springfield Armory.
The Springfield Armory got its start way back in 1794 as a producer and supplier of military weapons to the burgeoning United States military. This particular installation was responsible for some 400 Model 1817s in circulation before the end of the pistol's production run.
