Of all the guns I saw when I visited the National Firearms Museum last year, one of my favorite was definitely the S&W revolver recovered from the World Trade rubble. Its owner, Officer Walter Weaver of the New York City Police Department, went in to help but did not make it back out. The gun was identified by its serial and returned to Walter’s family who donated it to the National Firearms Museum.
