Bullets don't use models.
Bullets in GMOD don't even exist. They are raycasts(or raytraces), the effect you see is only a particle effect, which is a 2d sprite drawn along a line with delta timing to give the illusion of motion, when no physical entity is shot at all.
However, one thing I could do is make customizable weapon tracers, but then again, someone would see your custom tracer and know you're shooting at them, so it's not a good idea.
