I recently inherited my Great-Grandfathers WWI 1911. It's a Springfield Armory 1911, and according to the S/N was manufactured in 1915, in the second batch produced that year. I know the MSH and the trigger have been updated, but the pistol has never left the family. I'm assuming my Great-Grandfather had it altered after the rounded MSH and triggers were introduced. I have ZERO interest in changing anything on the firearm. I keep it clean, oiled and in a safe place. I had it checked over by a local gunsmith to make sure it was still in good shape. After getting a positive check I took it too the local range and fired off a few rounds. Other than 'hammer bite' it was a wonderful experience. Fires like it just came off the line, and dead on accurate! I also got his leather riding holster, several magazines, his dress sword, and magazine pouches.
