This is NYPD Ofc. Walter Weaver’s Smith & Wesson model 640 back-up firearm that was uncovered in the rubble of the World Trade Center after the 9/11 terror attacks. Ofc. Weaver was last seen on the sixth floor of the North Tower on that day helping survivors. The NRA Museums’ Facebook page displayed this photo montage today. Ofc. Weaver’s service and sacrifice are not forgotten.
