That's a gorgeous gun. And a really nice memento of your grandpa. Very cool.
I figured this would make a nice addition to this thread. This is the revolver my grandfather received for the 50th anniversary of the Arkansas State Police. It has never been fired but is an absolutely stunning gun.
Wow... How cool.
