Currently overseas near Russia, have a friend who claims to have a 1911 from WWII. He says it was his grandfather's who brought it back from the war. Is there a way for me to import it to the US if he wants to sell it? I thought I had heard there were problems importing military weapons back to the US after they had been given out. But, I thought I would ask and see if there was something I had heard wrong or if someone knew the correct way for me to bring the pistol back.
