I saw some chords for one gun, the only one so far, and played it but it just didn't 
right, so here is a one that sounds right.

  Dsus2                D         Dsus2               D
          Hey there pretty girl can I kiss you?
 Dsus2                D         Dsus2                D
With all you've said to me I think I'll miss you
 Dsus2                D          Dsus2                D
Dsus2                D
And she said, no one can kiss me while people scream
 Dsus2                D
They're screaming for me

 Dsus2                D
One gun added on to the one gun
 Dsus2                D
One gun added on on on
 Dsus2              D
One gun added on to the one gun
Dsus2                D
One gun added on on on
 Dsus2                D      Dsus2        D
Hey there pretty girl what is with you?
Dsus2                D       Dsus2             D
Don't you know the love that wants to kiss you?
Dsus2               D       Dsus2           D
And she said, "You may dream believe I see
Dsus2              D        Dsus2             D
All the people who are in need"

Dsus2              D      Dsus2              D
Hey there pretty girl I will let you
Dsus2              D     Dsus2              D
Do just what you want until I can get you
Dsus2             D       Dsus2              D
And she said, One more gun set free makes people scream
Dsus2             D
They're screaming for me
