War trophies are really common for gun shops/shows, due to the proximity between gun culture and professional soldiers (who actually collected the trophies).

No, they really aren’t? I live in Oklahoma, there’s a gun store every couple blocks. I’ve never been in one that has any real Nazi war loot, nor one that regularly displays Nazi memorabilia.

That’s for the gun shows, where they sell a ton of replica Nazi memorabilia. I’ve never seen a historical piece displayed or for sale.

More than likely, anything you’ve actually seen at a gun store or gun show are just reproductions.
