A fake silver chain stopped a bullet and saved a man’s life last month, police said.

The Commerce City, Colorado, Police Department said two men were arguing when one pulled out a gun and fired.

“The .22 caliber bullet was fired during an argument and would have ended up in the victim’s neck had it not instead become lodged in the chain he was wearing,” police said. “As a result he suffered only a puncture wound.”

Police said the suspect has been charged with attempted murder. They did not name him or the victim.

The department said it didn’t know what metal the chain is made from, but that pure silver, which is soft, would not have stopped a bullet.

“So maybe think twice before you knock a knockoff,” they said.
