Chord/Tab song: The Gun

Ok, so I saw RockNRolla and I loved this song but couldnt find a tab for it. I
pick up my guitar, and im pretty sure the whole thing is just a D chord and a G
chord. Try it out, I think it sounds fine!

D... G... D.... G...x 4

[D]The man has a gun, he knows how to [G]use it
[D]Nine millimeter Browning, let's see what he can [G]do
He'll point at your m[D]outh
Says that he'll blow your b[G]rains out
[D]Don't mess with me, carrying a gu[G]n
Carrying a gun[D], carrying a gun[G]
Don't you mess with me, carrying a gun
Carrying a gun, carrying a gun
Don't you mess with me, carrying a gun
Get over there, move slowly
I'll put a hole in your face, if you even breathe a word
Tell the lady to lie down, I want you to be sure to see this
I wouldn't want you to miss a second, watch your wife
Carrying a gun, shooting with a gun, dirty animal
Carrying a gun, carrying a gun, watch
you face, carrying a gun
Carrying a gun, carrying a gun
The animal dies, with fear in his eyes, with a gun
Don't touch him, don't touch him
Stay away from him, he's got a gun
