As a father of two young men let me first say how sorry I am to hear of the loss of you son. From the post it is evident you loved him very much, and I am sure he knew it throughout his lifetime. I truly believe we are on the earth for the blink of any eye, and you will see your son again. God bless you and your family.
It is also evident your boy inherited some fine taste in pistols. Let the Walther be a source of joy for you and not a remembrance of loss. Remember the good stuff, and keep in mind you will see your boy again in better times.
