Intro: G Cadd9 G Cadd9

    G                          Cadd9
It sets above the mantel on a couple rusty nails
          G
It ain't worth a lot of money
       Cadd9
And it damn sure ain't for sale
     G                             Cadd9
The good lord only knows all the stories it could tell
                    G
My Granddaddy's gun

     G                                 Cadd9
He bought it new out of the Sears and Robuck catalog
         G                         Cadd9
And it shot a many shells over the back of an old bird dog
         G                                Cadd9
And it backed a burglar down when grandma took the safety off
             G
Granddaddy's gun.

     Cadd9                 G
It's just an old double barrel twelve
      D                      Em7
The stock is cracked and it kick's like hell
    Cadd9               G                D
It wouldn't mean what mean's to me to no one
            Cadd9                       G
Cause I can still hear his voice when I put it to my shoulder
   D                         Em7
A guns like a woman son it's all how you hold her
    Cadd9                G                D
He taught me a whole lot more than how to hunt
Cadd9                      G                D
And one of these days I'll pass it on to my grandson
                G
My Granddaddy's Gun

That old man gave it to me on the day I turned thirteen
With a half shot box of shells and a kit to keep it clean
I keep a picture in the case of that sweet old man and me
And Granddaddy's gun

Cadd9 G Cadd9 G

It's just an old double barrel twelve
The stock was cracked and it kick's like hell
It wouldn't mean what mean's to me to no one
Cause I can still hear his voice when I put it to my shoulder
A guns like a woman son it's all how you hold her
He taught me a whole lot more than how to hunt
And one of these days I'll pass it on to my grandson
My Granddaddy's Gun

          Cadd9                      G
There's a long beard hanging on the livin' room wall
     D                         Cadd9             G     D 
That I got with a box call and      Granddaddy's gun
          Cadd9                     G
There's a beat up sign out there on forty nine
     D
That me and Billy Joe shot up one night
    Cadd9            G     D
With    granddaddy's gun 

    G                         Cadd9
It sets above the mantel on a couple rusty nails
           G                         Cadd9
It ain't worth a lot of money but it damn sure ain't for sale
