Perhaps try browsing all files for the game Counter-Strike: Source and upload any files you want to share or are missing. This is the only information we could locate:
This is a reskin for the M3 Shotgun of Counter Strike: Source. This has been skinned apparently to resemble the shotgun of Resident Evil 4, which is evident in the wooden grip, and silver/grey color of the metal. The skin is failry detailed, mostly noticeable around the grip and the length of the barrel, especially the sides. There's a picture of the RE 4 Shotgun in-game there for reference purposes. This is a pretty good reskin for the M3 if you'd like to bring a little bit of RE 4 to your CS: Source fighting.
