Is There a Golden Sledgehammer in Red Faction: Guerrilla (Xbox 360)?

There is no "golden sledgehammer" weapon in Red Faction: Guerrilla for Xbox 360.

Possible Explanations

• Weapon Mod Nickname: The game allows weapon modifications; a gold-colored mod might be nicknamed this.
• Misremembering: The iconic sledgehammer exists, but not in gold. You may be thinking of another game.
• Modded Version: Xbox 360 cannot be modded easily; a gold sledgehammer would only exist on a modded PC version.

If you can share where you saw this (video, friend), I can clarify further.
