I think the vanilla Heavy SMG texture is too big and too lightly colored.
I remade it smaller and darker it to match the assault rifle and chain shotgun better.
Simply overwrites the vanilla texture file.
This can get overruled by any other mod that affects 'HeavySMG' texture and is lower in the list.
I recommend using a DDS texture mod to avoid the usual mod PNG texture compression:
