User blog comment:HybridX8/Should Rockstar make a gold gun pack DLC for single player?/@comment-2111288-20100607215548

Unlock gold guns, but they should also have some minor special version of that gun so it's not just gold plated. Like the gold bolt action could have a bayonet, the gold LeMat could make use of the under-barrel shotgun, etc. Whatever was specific to that particular gun.
