Item description:

Restores Barney's fingers and makes other minor corrections.

There are two different models for his hand depending on whether or not he's holding the gun. Originally, both hands appeared on top of eachother when he held the pistol, instead of one replacing the other. I'm guessing this alternate hand was left over from an earlier version of the model, since the skin tone on the textures doesn't match. Additionally, the normals on the holstered pistol were inverted, making it appear inside-out. Gearbox didn't fix these issues for Opposing Force and Blue Shift, either.
