Where'd this pistol sprite come from?

[Artman2004]

I was searching up the Doom pistol when I found this:

Can anyone identify the origins of this sprite?

[TenenteZashu]

pretty sure it's an heavily modified version of the vanilla pistol

[BerserkerNoir]

Ive seen that complete picture, it was in TF2 Doom like pistol mod.
The one who made it should know.
is Either an edited single sprite, or taken from somewhere else.
