Keep the Walther as a momento or remembrance of your son as you would a picture. Shoot it and appreciate your memories of him. I am sorry for your loss, but I have started to appreciate the time I spent with friends and family while they were still here more than mourn the fact that they are gone. Remember the good things and let the hurt go. You don't think your son would want you to hurt do you?
This is my gun. There are many like her, but this one is mine.
I'm not old. I'm CLASSIC!
