Blackhawk (Fallout 3)

The Blackhawk is a unique Scoped .44 Magnum given as a reward for bringing Agatha music paper. The sheet music can be found at any time, as long as you have access to Vault 92. If you failed to locate the sheet music inside Vault 92, there are copies in Springvale Elementary, Arlington Library, and Roosevelt Academy. This is also an extension of the quest Agatha's Song. When Agatha gives you the pistol, it will be at half condition - it can be repaired with any Scoped .44 Magnum. It is one of the most destructive mid- to long-range small guns in the game. Even Enclave Soldiers and Super Mutants can easily be decapitated by one well-aimed shot to the head.

Note: When giving Agatha the music sheet, you MUST request a reward, or else she will not give it to you.
